Re: Tor takes too much RAM

It does have vmstat. I should point out, however, that vmstat shows
pretty much the exact same stuff that free does, only with less math
done for you, a few important missing numbers, and a few added numbers
which aren't really important in this case.
(This is a different server, which is why it has more RAM)

Tor is currently disabled on that first server because I run other
things on it that I'd rather stayed functioning :) My relatively small
90mb usage is pretty meaningless compared to the 1.5gb usage of others,
though, and on my other computer it's using 136m RES according to top.

So how was your system affected? Was there heavy paging going on?
Or worse, swapping? Those are what one would expect when there is a lot
of contention for the available page frames.
It's not a local system, so I didn't have an easy way of seeing a hard
drive indicator. I can tell you that I was having literally
thirty-second-long delays just trying to use the command line, which
went away when I killed tor. So I suspect it was swapping like a mofo.
