i'll dig up a debian box.
My children are pegged at 6-13MB of private memory, on top of
80mb ?!? of parent memory
That doesn't sound very big to me.
Really?
I was under impression that with proper memory management, you could
have MP servers down to around 3-6 MBs (at least the modperlbook and
docs suggest that )
I tried doing some dumbed down servers/handlers where the only thing
involved was the Apache2/APR libraries-- on first hit the children's
memory spiked to 6mb each.
Lots of things won't be shared. Just reading a variable can
unshare the
RAM page it's stored in. It should not be growing on every hit
though.
If you run one process and hit it with ab doing the same request over
and over and it keeps growing, you have a code problem.
i thought unshare on read should only happen if you're accessing a
string as a number of vice versa. I'll see whats going on once I've
got the Debian box up. The 12MB just seems too big.
I have a slight grow , about 10k per request. I need to track that
down. I think that should be normal, and I've got max-requests set
to 1000 so it never gets out of hand.
I'm glad you don't think thats a big size though. It was a lot
larger than I was expecting.
