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.
From sysctl:
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?
