Computer Optimization


I. PART – INTRO AND FRAGMENTATION

Many people feel that computer performance is deteriorating with age. I want to dispel this myth: computers are mostly solid-state technology, which is largely influenced by age. I'm not saying that older computers do not run slower, but after we've made the announcement that the slowdown is caused by their unchangeable age, the problem will be what can usually be remedied without buying another computer.

First, let's understand what does not cause the computer to slow down:

  • Computer processors are digital electronic transistor switches that are locked in hard plastic packaging; These are devices that are in solid state that either work or not. It can bake if it is exposed to overvoltage, but otherwise it does not slow down.
  • The computer's memory is composed of similar components, or it does not work, as well.
  • A computer motherboard is nothing more than a piece of plastic, usually attached or soldered with more solid-state devices. Motherboards do not slow down either.
  • Computer power supplies are the most extreme of computer experience. This is why they burn more frequently than most other parts, but they do not cause performance drops; or are they working or not.

So what is causing the computer to slow down with age?

The biggest culprit is the storage of data. Imagine trying to find something in a filing cabinet if it was the only item in the drawer; it's easy to find it, do not you? If there were only a few items in the drawer, it would be easy to push them inches to find the desired one. What if the account is fully filled? It could take a little longer, right? This is what happens on the hard drive when you install an operating system, applications, and data. Each time you download multiple.mp3 songs, you can import more.jpg photos from the camera, or write new word processing documents, and load new stuff in the file cabinet that is your hard drive.

Unlike the processor or memory, the hard drive is generally not a semiconductor device; moving parts. Consequently, the time needed to read or write hard disk data is 1000 times slower than solid state devices such as RAM or USB flash drives. Couple with the fact that adding more stuff to it and starting to understand the problem.

In reality, worse than imagining. If a document is saved to the hard drive, it will be stored in a specific location on the drive. The computer tries to allocate the hard disk space as efficiently as possible, so if you write more things into the drive, it will be stored in the next available sequential space. (Hard hardware experts read this, yes, I know this explanation is severely over simplifying the process.) Unfortunately, if this initial document is edited afterwards, there are no interrelated areas in the drive that are stored in the new data so that the documents from the first part you can separate storage stored elsewhere. Later, when you try to read this document into memory, it takes a little longer than a continuously stored document because the computer needs to read its middle to find the rest of it. This is the separation. Another reason for the fragmentation is to delete the files as it creates holes that the computer tries to fill in from bottom-up data, but the holes are almost never the size to save the new files, so the newly saved files are also inseparable.

Do not think your use is the only force that drives the drive to fragment. Virtual memory, recent files, various cache files, and updates / fixes always use and release the hard disk space that causes fragmentation, even if you never deliberately save another file to your computer. Fortunately, fragmentation is reliably easy to cure. Microsoft Windows comes with a device that we – all you have to do is use this tool from time to time and rearrange the files on your disk that will do everything to keep them all the time. We're lucky, so many things we store on hard disks do not change every so often. Operating system files, installed applications, and even our music and photos rarely change in content or size, so if the hard disk has downloaded fragments to less dynamic areas, then it should be fine.

II. PART II – DIGITAL RISK

After the fragmentation, the next question about hard drives slowing down our computers is the growing amount of data. If you've seen a voice recorder, there's a rough idea of ​​how the hard drive works, but imagine it spinning much faster. Instead of 33 or 45 rpm, hard drives work at 5400, 7,200, 10,000 or 15,000 rpm. To make the slow hard disk that can turn to the opposite side of the disc can be 1/100/1 second, but as a phonograph turntable, rotation is not the only movement the drive does; the head is radially in and out and this movement is considerably slower. If there is little data on the hard disk, this data is usually stored near the center so that the head needs to pass only a small portion of the disk's radius but more data is stored, the larger the radius of the disk is used, part that the head needs to travel takes a longer time, so data is read and written slower.

Fortunately, this kind of performance deterioration can often be alleviated. People are generally terrible about rats about what they store on their computers. Hard drives will be like gathering black holes, years of data that can never be used, not needed or even seen. If your computer was faster when it was new before it could belong to all of these data, you may be able to reset it to performance levels if you can clean the data. There are many ways to identify and remove unnecessary data from your hard drive. Windows comes with some tools that can help:

  • Disk Cleanup keeps track of multiple spammers left on the drive and allows you to remove them.
  • Add / Remove Programs helps you find and remove old apps and Windows components that you no longer use or do not need.

Even old documents, music, movies, and photos can be assigned and deleted or moved to offline storage (such as a CD or DVD or network or web storage).

In extreme situations, you can reduce the size of some caches, such as the System Restore cache size, or even the Recycle Bin. By default, these 12% and 10% of hard drives are picked up, and if you do not mind deleting unwanted things, they will be released in 1/9 of the hard drives without any undue risk.

Professionals can also help you find additional ways to free empty spaces, such as disabling Offline Files, if you do not need this service, delete old user profiles, remove old printers, reduce Internet caching settings, and more. leave the remainder behind the hard drive, even after removal; they can also be deleted. Poorly configured virtual memory settings can take advantage of the hard disk more than you really need it.

In addition to storing hard disk data, there is another area where computer performance is deteriorating, and due to age, requirements for processor and memory increase. However, this issue needs to be divided into two categories. One can be done without updating the computer, while the other would probably not be.

The unlockable category is what I call "Application Peak." Your computer probably has a lot of free and free trial programs you've never used. Most of them are on your hard drive while you are sleeping, but some are like printer drivers, malicious detectors, and hardware and software refills when you load them whenever you start the machine. In addition, he probably installed more, whether he realized it or not. If you installed Adobe Reader, there is a small snippet code that is likely to be replenished every time you restart the computer – it makes it faster to open.pdf files because Reader is already in memory, but what about 99% of time do not use it? Well, he's still sitting there, picking up resources and slowing down other operations. Many other common applications have components that start automatically when you start your computer (also known as "AutoRuns"), such as iTunes, Safari, QuickTime, Java, and other devices. Besides these AutoRuns, other unwanted programs are covered with piggy-backed programs. The extra toolbars in the Internet Explorer window have been a carefully understood payload of many other programs installed and guess what – unnecessarily using the resources every time the IE runs. It's not a big achievement to realize that when unnecessary resources are used, desirable operations work less efficiently.

The hard-to-reach category is the result of technological progress. He bought his computer eight years ago before Netflix started making movies and is now looking forward to doing things he did not want to do. You've finished playing games and bought new games, even though they require more RAM, more hard disk space, and faster processors. You've been a movie camera before, but now import the pictures of your digital cell phone from all your travels and you've started making short videos! … and even if you do not actively update any software or increase your use, updates can take place behind the scenes. Microsoft Windows can automatically update itself and actually set up a number of Microsoft software addresses. Adobe, Java, Real Player, iTunes and Quicken ask for updates, and just click the "OK" button without thinking about it. Bug fixes come out, updated drivers are released and you do not want them vulnerable or outdated, so you accept them. Each update contains additional statements for the computer's resources.

Let's see, we still do not carry our first brick-sized, analog, battery-powered, mobile phones – we want the latest features, so we're updating it. Sometimes you have to make a decision with your computer. Lastly, even after data thinning, it may even remove unwanted applications and clean up AutoRun programs as long as you are reasonably aware that your computer is still too slow for your taste. Upgrade or replace at this point. Hopefully, based on these tips, you can at least increase the time between computer upgrades to save money.

IV. PARTY – AMOUNT

So you've tried optimization and are still dissatisfied with your computer's performance. Now what? Maybe it's time to upgrade, but what needs updating? The whole system? Only some ingredients? If time and money were not the subject, just buy the latest great system and hire someone to reinstall and modify all of your applications and transfer all your data. Unfortunately, many of them are not the case. When faced with limited resources, decisions on the best ways of employment have to be made. I did not hate to spend four digits on a completely new computer system if all of the old ones needed a memory upgrade. However, you hate being able to waste money on RAM alone, you have found that you are still dissatisfied and still face the need to buy a completely new system. How can you tell what to do?

Windows has a number of tools to help identify bottlenecks. By disciplining this information, we can make better choices about what to do to solve them. Here are some of the more common bottlenecks: a low-speed network connection slows down Internet access and other network resource utilization.

  • Network Connection –
  • The main memory which forces the computer to use a swap file on a hard drive with inadequate RAM slows down processing, task switching and read / write operations.
  • Processor – with too slow processor or too few processors will affect the performance of all operations. The less expensive processors do not have the L1 cache, which further reduces their performance.
  • Hard Drive – Slower hard drives affect the speed of all read / write operations, including cache and virtual memory. Space is also taken into account; according to the guidelines it uses less than 50% of the capacity of the hard drive.

Try diagnosing the problems first to diagnose problems. If your performance complaints primarily target web load speeds, you may be more likely to report a problem with your Internet connection speed. If performance gets slower, if there are more applications running, you may have insufficient memory or a slow processor. If the hard disk drive light is on frequently, it may indicate insufficient memory or too slow or too large hard disk space. Having found your guess as a starting point, you would like to find evidence in or against the dissertation. A good starting point for Windows Task Manager. Press Ctrl-Alt-Del and the Task Manager or its link appears, depending on which version of Windows you are running. The Performance tab shows the processor and memory utilization, and the Network tab shows the utilization of the network connection.

Let's start with the power's ear; provides a lot of good information. First, the number of CPU Usage Stories fields shows how many CPU cores are used. Usage may generally be low unless a lot of bets are actively run. If any of the graphs record the pen with the filter on top, multiple applications are placed on the processor than they can handle. The PF Usage Graphs show how much RAM is used. Ideally, you want it to be low. The more applications running, the more RAM you need. As mentioned above, after the computer runs out of actual memory, it creates more space for moving less frequently used data into "virtual memory", which is actually stored on the hard disk. If needed, it replaces the following least commonly used data on the hard disk to provide space for the data to be exchanged. All these operations require time, so if using PF at the top of the graph is not enough RAM to suit your needs.

Another useful tool to view the processor and RAM installed on your computer is the Control Panel System Properties. Press the Windows-Break command to set it up. The Pentium-4 processor is standard today, and if it's older, I would not interfere with the upgrade – just replace the computer. Different operating systems have different memory needs, but at least there is at least 1 GB of RAM.

Back to Task Manager, do not be surprised at the Network Management tab if network utilization is often under or below one percent. The typical desktop computer network interface card (NIC) can communicate at 100 or even 1000 million bits per second – even older network cards can communicate at 10 Mbps. A typical broadband Internet connection (for example, a cable modem, high speed DSL or fiber optic connection) works in a 1 Mbps environment and only when it downloads large files under perfect conditions. If you are connected to other local network resources (such as servers or network printers), you will probably use more of your available bandwidth, but if your only network utilization is network access, bottlenecks will always be the Internet connection instead of the computer's network connection. Now that this has been hacked, if you find that the graph shows a 100% or approximate recovery, your network card may be too slow for your needs, but if you do not feel comfortable with the speed of your web pages, using a small, low network connection, you must update your Internet connection instead of using a computer.

PART V – GENERATION

Now that you have recognized the problem, you have to decide how to deal with it. Some issues can be solved with minor fixes, but others can not afford the costs and troubles and are ideal for replacing the computer.

If you have chosen not having enough RAM, this is usually the cheapest and easiest upgrade you can bring to your computer. Depending on how many memory cards there are on the motherboard, you may be able to install additional DIMMs or replace existing low capacity DIMMs with larger capacity. There are dozens of incompatible memory types, so if you're not sure what you need, the simplest way is to look at the owner's manual that came with your computer. You still got it, right? If not, remove the DIMM and bring it to the store or if you buy online, look for the make and model of your computer, not the memory type.

If you have decided that the network card is too slow, you can probably install it faster in an open slot or even in a USB port – this is a relatively inexpensive and easy upgrade. Most PCs in the past 10 years have a PCI expansion slot, so you can probably look for a PCI-enabled network card (NIC) in your local computer storage or the Internet. They come in wired or wireless varieties, depending on how you can connect your computer to the network. If you are unlikely to open your computer, both wired and wireless network cards are now available in USB versions. If your Internet connection is too slow, you do not have to work on your computer – just contact your ISP and talk about options to offer service upgrade to higher bandwidth – or buy around to find out what other ISPs are doing.

If you decide that your processor is not enough, then you only have the option of replacing your computer. The motherboards are designed to work with a small group of different model processors, and even if your own low cost model, cost reduction, and high-end processor upgrade costs do not result in noticeable improvements; Replace the computer with multiple processor cores. The only exception to this rule may be that the motherboard has allowed the processor to update the processor with L1 cache (eg, Celeron) L1 cache processor, resulting in a remarkable improvement that guarantees costs and difficulties. If so, check the owner's manual (or online specifications) to see which experts find the motherboard and if you decide to do the time and effort costs it's probably best to get the best and fastest available – you do not want to do this again in a year when you get a tiny, incremental improvement.

Historically, when the computer hard disk became a bottleneck, it was usually a point we recommended to replace the entire system. However, in some cases the rules have changed. Replacing the hard drive includes reinstalling the operating system and all applications, and transferring all personal files and data, so it is typically a laborious process that provides the ideal time for the rest of the PC with it. However, today, due to the popularity of digital photography, .mp3 music files, videos, and other compelling multimedia data, it is often possible to optimize an existing hard disk drive for external storage of such personal files and data. USB flash drives are available in 64GB or higher and external USB hard drives are larger than 1TB (1024GB). The help of the utility is that you have to change the installed location of most applications and the Windows component, but moving data files is much less trouble. In fact, to further improve performance, you can free your computer's virtual memory file to a second (internal) hard drive without too much trouble. As mentioned earlier in this dissertation, the more things you have on your hard drive, the less effective it works, removing all non-system critical data on the hard disk that includes the operating system and applications, you may be able to recover most computer-based youthful performance without too much trouble.

Ultimately, these optimizations and updates are just stop-gap measures. Software patches and updates require more space on your main hard drive and are likely to add more features and applications over time. Even if it is terribly pitiful on the main hard drive, there are still growing demands. This is also one of the few mechanical components in the computer, so their life expectancy is expected to be shorter than any solid-state component. At some point, you need new major hard drives, and at that moment I still insist on my situation that this is a good time to replace the whole computer.
