Speed Demons

There is an issue that I feel must be addressed, since the issue continues to come up on a regular basis. As a PC technician I constantly get asked why the clients' computer has become so slow, and if there is anything wrong with it.    The first thing I tell the client is that there are two main culprits that contribute to a PC becoming very sluggish. The first being lack of RAM memory. This answer usually elicits a quick response from the user that they "only do e-mail, Internet and word processing" or some similar response. I then go into a discussion with the user that there are two kinds of memory in a computer: hard drive storage, which holds all their music, pictures, documents, etc. and RAM, or working memory. A user could have plenty of hard drive space to store all of their documents and stuff, but when they don't have enough RAM, the computer will, over time, become slower and slower.    Why you ask? When the computer was originally purchased (usually somewhere between 2 and 5 years ago) Windows XP, in this case, required about 512MB of RAM to run properly. As Windows critical security updates and service packs are installed, as well as upgrades and updates to all sorts of programs used on a daily basis (antivirus, Internet Explorer, AOL, Adobe Reader and Flash Player, printer updates, etc), the programs NEVER get smaller, always bigger.    Now, several years later and the programs being used are double or triple in size, but the computer is the same one with the same specs as when it was purchased. Adding more RAM memory is a quick, cheap way to improve performance to an aging computer, and extend life before a replacement is in order. Windows XP should have at least 1024 MB (1GB) of RAM to run properly, and Windows Vista (32bit) needs 3GB of RAM. More is not better in the case of Vista for technical reasons I will not go into in this article.    This is only half the battle. The other half is to beat down what I will call the "moochers". Years ago when I would inspect a computer for sluggish performance, it was usually because of a rogue game that was installed. Back then quite a few games adopted the theory that the only reason you owned your $3000 or $4000 computer (yes, it was that much back then, even more depending on how far back you go) was to play some ridiculous $49 game. The game would change many settings that allowed the game to work properly, but made it miserable to perform simple tasks like type a letter.	Now, in 2009 every program under the sun assumes that they are the main focus, and must be given priority at all times. What does this mean to you, the end user? Each time when an upgraded revision of Adobe Reader comes out it always wants to include the new MSN Toolbar or Yahoo Toolbar etc. This adds unnecessary junk to your browser, which slows down getting online. In addition, many of these programs load an additional program when Windows starts to speed it up when starting it. This is just lousy practice that is a very poor substitute for tight efficient programming. If the program was small and lean there would be no need for speed loaders, which make your computer take an exorbitant amount of time for Windows to start.    Not to pick on, but a classic example of this is how much Apple's iTunes has grown through the years. iTunes 6 which was released in January 2006 was about 35MB in size. iTunes 7.5 was 52MB and iTunes 8.1 (the current release) is now up to 70MB. The program is twice as large only three years later, and loads a number of programs when Windows starts to aid loading this memory hog.    What to do about this? In short be mindful when installing updated programs to unselect add on toolbars and, if available, to kick them out of starting up when Windows loads. I have discussed at our local computer club meetings to do your best to keep running processes to a minimum. By clicking control, alt, delete once (with no programs active) will bring up the task manager and show how many processes are running. A good number for Windows XP is less than 35, and for Vista it's about 45.    Startup Cop and the free CCleaner utilities have the ability to disable or remove programs from starting, but I would check online in a Google search before disabling anything unless certain. I do hope this article sheds some light on the subject of pokey computers. Remember, it's not so much the hardware as it is software that kills a computer! Until next time!    This article has been obtained from APCUG with the author's permission for publication by APCUG member groups; all other uses require the permission of the author (see e-mail address above).
