How would you go on with adding call graphs without
adding too much overhead? I think it would be hard to
beat gprof on that one.

worst case looks like probes have been
running for 8.9secs straight, seems unlikely.
So there seems to be a need to get hires profiling
uptodate with current squid code base.
Unfortunately, I can't participate for now, my company
has been restructured and caching has been thrown out, so
I don't have any suitable platform at the moment.. ;(

Wouldn't this kick in in accelerator configs?

to wrap it up into some form of
ifdef'ed debug option into mempools, or would that clutter source
needlessly? It isn't perfectly portable I guess, so, I don't know.

is limited to 64, meaning no more than 64 chunks would get mmapped.
That seems abit small.
Finally, dlmalloc latest version has thread_safety options.
Rest, internal tunables are probably indeed not needed.

Hello,
No comments on this one. Would someone please review proposed fix
if it is correct one for CVS?
Seems same bug as:

+SQUIDCEXTERN void fwdServersFree(FwdServer ** fs);

As there are quite many such places I suspect something is wrong on my end.
anyone point me to right rtfm?

unkillable process means problem blocks inside kernel.
My bet would be buggy kernel threads implementation, especially
that fsck after reboot hints that ext2 was corrupt already when
squid hangs. Try diskd instead of async-io on linux.
Other bet would be faulty hardware or non-ECC memory get
voiding OS support, so, imo, it would work as well
on plain FS as on any other approach. The only reason to go for raw disk
or O_DIRECT would be if we want to keep ram usage to very minimum, ie for
very lowend boxes.

afaik all network ops should be accounted by profiler, by means of
w/read_handlers in comm_poll at least. But I haven't looked after 3.0
How large is prof_unaccounted during normal high load? If its more
than 1-5% then something substantial is unaccounted for.
Is it possible that more than 2
Prof_unaccounted gets assigned time during which no timers are active.
Most probes that are there have been added ad hoc to cover most busy
parts of squid. Thus we can assume that cpu is hogged by some section
of code thats not normally very cpu intensive.
You could try either add more probes
same url have to go to
origin?

hi,
we should really avoid fopen() in any place. it may fail when
first 256 FDs are in use. Cause of failures during reconfig.
