lastly, if it will make someones choice of the platform easier: same test.php on P4-3Ghz-1Gb, FC3-386 shows 540 RPS - comparable to Athlon 3000+ results on FC3 i386, but noticeably lesser than what same Athlon shows in 64 environment.

I forgot to mention -m64 flag that I also used.

ok, here is the complete details:
Athlon64 3000+ (it's +20Mhz overclocked on the bus, i.e. running on 220Mhz x 9 - roughly on par with Athlon64 3200+). NForce Ultra (MB: tyan k8e) with 1Gig.
php 5.0.4 + 1.3.33 statically compiled with -O3 -msse3 -m3dnow -march=athlon64 -mcpu=athlon64; (can't recall if I did unroll loops and omit frame pointer)
no extra switches or additional modules for configure.
the test.php script looked like
<?php phpinfo(); phpinfo(INFO_MODULES); ?>
then tested with /usr/local/apache/bin/ab -c 50 -n 20000 http://localhost/test.php
FC4 x86_64, kernel is 2.6.11-1.1363_FC4 - the RPS is 730. FC3 x86_64, latests kernel - same results. FC3 i386, latests kernel - 570 RPS. FreeBSD 5.4-RELEASE (x86_64, stock kernel) - 670 RPS
same hardware in all tests, same optimization switches during compilation.

I've compiled apache+php and measured max requests per second (rps) of a simple php script (output of phpinfo(); php_info(INFO_MODULES)) with the apache's 'ab' application. The maximum RPS I managed for FC4 is 440 while FC3 showed up to 730. Network is not the issue cause I did measurement via lo0.
It's the same server and I've ran yum update before tests in both cases. Any ideas?
If you are running a kernel earlier than revision 2.6.11-1.1355, it'll have extra debugging enabled which will impact memory allocations.
I did the tests several days ago; following your advise I just ran yum update and tested once again with 2.6.11-1.1363_FC4. Things are much improved now.
Great! However, don't tease :-) I'm sure I'm not the only person curious what RPS you now achieve :-)
