Can you or anyone else tell me where to find more information about how
to interpret a processes' virtual memory stats as given by top or ps on
linux (and/or other unix-like systems). This has been bugging me for
quite a while now.

man ps

s size memory size in kilobytes

i

A good explanation on why they're useless (as you claim) would also be
good. I'm just trying to figure out what's what.

ps: my ps manual claims that -vsz memory is reported in 1Kb blocks (not
4k blocks as you stated)
