The idea of caching sounds nice, but because computers today don't have much
RAM it just makes computers run slower. I think that the current Linux
distributions still assume that people are using powerful servers and not low
memory workstations. For instance, M$ Win32 systems do the same thing as Linux
in that they take up all available memory and cache it. However, on any normal
system with dozens of high-powered programs, the cache runs out in no time
flat. When I used to use Win32 I set the default cache as 4 MB, and my computer
ran considerably faster because 20+ MB of RAM was freed.
I am currently looking for an option in the Sys V Init files to reduce the
cache. Maybe it's all for nothing, but it's worth a try.
