Still, with fs_usage PID, I get more the 57k lines of stuff... I've found
another tool that is more appropriate to monitor system calls : sc_usage.
This tool gave me this :

Which tells my that my last asumption is right, it's file-system related.
The process passes it's time at :
- System busy and idle tasks for 6 seconds
- read for 4.8 seconds
- getdirentries for 2.2 seconds
- httpd usermod (I assume that is php processing time, nothing wrong here)
Since I am a registered Apple developper I will log an incident with apple
for this. I'll let you all know
And Richard, I must rule out the mysql problem. As stated before, on two
hardware identical machine, one with 10.3, and one with 10.4. The mysql
database is on a third different machine. So connection time should be
identical. Besides, with the trace i've done with micro-seconds timestamps,
the majority of the time mysql_connect takes less than 0.01 seconds.
As for includes, again as stated before, all is the same, including config
files, thus include_path, wich only contains /usr/local/lib/php, and this
directory contains the base PEAR installed over time plus one or two other
file.

You certainly wouldn't want to do just fs_usage. Typing something like
"fs_usage httpd" will show you just what the httpd process is accessing.
Read the man pages for other options that may be helpful.
I've got a few things running on OSX 10.4, although none that handle lots
of traffic. Public sites:
dutchessfootball.com - a football pool, the picks page is the slowest to
load. That's on a single cpu 1.25 G4 512MB RAM
heardthroughthegrapevine.com - wine tasting site, nothing fancy or that
complicated. That's on a 400Mhz G4 384MB RAM.
The big application is internal to my company and has about 285 "web"
files total, and about 45 mysql tables (contacts, companies, resumes
invoices, jobs, emails, journal,etc). They all have lots of includes
since I use a custom templating system to separate php from html. I do
not use PEAR or any content management system, I found them too slow. I
know a few people who have looked at Mambo and rejected it because of
it's CPU load, although they were all using Windows servers. I've never
looked into why Mambo has high CPU requirements.
Is it just the Mambo parts you are having problems with or is it php in
general?
With 100% CPU, we've narrowed it down to something there. Now we need to
figure out why the CPU is the bottleneck.
