Subject: [gentoo-user] managing RAM usage

1 I'm trying to maximize the number of servers I can run on my machine
2 without running out of physical RAM. I noticed something strange when
3 comparing top and free statistics:
4
5 top says each PID associated with a particular server has a RES of
6 about 100M. Does that mean each running instance of that server
7 reserves 100MB? Since there are 20 of these servers running, this
8 seems contradictory to the output from free which indicates less than
9 1GB used -/+ buffers/cache.
10
11 Is there any way to monitor RAM usage over time to see how close I'm
12 getting to using all of my physical RAM?
