So I'm experimenting with postgres on netbsd, using a small database...
box has 512MB RAM...
load averages: 3.62, 3.58, 2.86 up 0 days, 7:04 19:53:20
91 processes: 90 sleeping, 1 on processor
CPU states: 9.5% user, 0.0% nice, 18.4% system, 0.5% interrupt, 71.6% idle
Memory: 300M Act, 147M Inact, 1068K Wired, 11M Exec, 399M File, 336K Free
Swap: 129M Total, 129M Free
..swap space never seems to get used.
vm.filemax = 50
399/512 is around 78%...
What's going on here? I imagine the buffer cache is full of mmap'd
bis and pieces but why is it so high?
