In addition to what Brian was talking about, Linux specifically, takes a slice
of RAM and puts it into the memory CACHE.

vis (on a AMD K4 64M & 128M swap)
(this box is my internal squid cache for a few users)

yoda:~ # free

Mem: 61800 49928 11872 0 5400 21572

It also helps if you spread your disk load over multiple disks & controllers
to lighten the IO load. More memory (RAM) is also good.

A client of mine currently uses four P3 boxes with 512Mg ram (, FreeBSD &
squid) connecting into two front end high end Netscape proxy boxes(Sun
E450's, 2G ram, x2 333Mhz) for internet access for around 100,000 users in a
banking environment.. and it rocks...
