How are you defining "available memory for apps"? Are you having=20
applications crash due to lack of memory?
NetBSD, especially 2.0, is very agressive about caching lots of=20
recently-used data. To the point that you can tune it so that any one user=
of memory can gobble all of it up. Thus you can easily have all of the=20
system RAM working for you.
As a consequence, a heavily-used system will end up with very little=20
memory just lying around doing nothing. I've seen busy half Gig and 1 GB=20
systems happily running with 1000K "Free".
