This is about my old computer, Windows XP SP 2 Home Edition. Also: HOSTS file, Avira security suite. Not long ago this computer started to have performance issues, especially after boot. I think I know why. Sort of. The system has 512 MB RAM. At times, the system uses almost 512 MB RAM, sometimes more than 512 MB. Which could account for the slowness. Sometimes I can hear the computer accessing the harddrive when it's sluggish. It took me some time to figure this out, because I have difficulty using the task manager at times, it's that sluggish ! Also, my computer seems to freeze sometimes, or something close to that. When did this start ? I'm not sure. I restored a known clean image, and got the update for MS-Word. Since I have SP2 I won't get any updates for Windows, only for other Microsoft updates. I have seen the process for Microsoft updates (or Windows updates?) running frequently, consuming CPU resources. Also, svchost seems to take a lot of memory at times. I don't run third party applications (aside from the Avira security suite) that consume much memory, this computer is used for internet access only. Anyway, I know I can disable the paging/swap file, but what is the best way to deal with this ? I really don't want my computer to use the harddrive as memory since that's too slow. Perhaps full use of the 512 MB RAM is bad too. Any suggestions ?
