Profiling PHP

Hi all,

I'm trying to find a performance problem I've got in a reasonably large
system I'm writing. Anyway, I've had a look around at the offerings for
profiling php requests...

xdebug : seems to make my requests just hit the 30 sec timeout all the time.
apd : segfaults every time I make a request
dbg : no front-end for linux (I looked a phpEd but it seemed to suck, and I
couldn't see how to get profiling info out of it) ?
php-profiler : has to be applied as a patch to php source, I don't want to
compile my own sources (box is debian-unstable, I'd rather keep everything
as standard as possible than screw things up locally installing major
things like PHP).

Are there any other solutions for profiling the execution of a php request
that I've missed or is this it and am I gonna have to start picking stuff
apart in my code to try and isolate the problem ?!

---
Cheers.

re: Profiling PHP

Probably one of those zend products. I saw the debugger in action and it
seemed to work quite well.

As for the 30 sec problem, have you tried set_time_limit(0)?

re: Profiling PHP

One time I installed phped/Linux and it worked under Redhat 7.2, never
tried since that. I'm working under Windows and phped works better
under this platform. Profiler is really incredible, time resolution is
about some microseconds, sufficiently good for all of us.
BTW, dbg is the first and seems the only good profiler for php :))

JV.
