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 :-)
