Linux is sorta like SunOS: shared VM and buffer cache.

What is better is really application dependent.  I have apps that do 110
MB of disk I/O in <1 minute, and they push everything else out on SunOS.
That sucks.  OTOH, other apps (such as big compiles) work much faster
on SunOS cuz all of the includes stay cached.
