Apache2 benchmarks - very poor performance
- by andrzejp
I have two servers on which I test the configuration of apache2.
The first server:
4GB of RAM, AMD Athlon (tm) 64 X2 Dual Core Processor 5600 +
Apache 2.2.3, mod_php, mpm prefork:
Settings:
Timeout 100
KeepAlive On
MaxKeepAliveRequests 150
KeepAliveTimeout 4
<IfModule Mpm_prefork_module>
StartServers 7
MinSpareServers 15
MaxSpareServers 30
MaxClients 250
MaxRequestsPerChild 2000
</ IfModule>
Compiled in modules:
core.c
mod_log_config.c
mod_logio.c
prefork.c
http_core.c
mod_so.c
Second server:
8GB of RAM, Intel (R) Core (TM) i7 CPU [email protected]
Apache 2.2.9, **fcgid, mpm worker, suexec**
PHP scripts are running via fcgi-wrapper
Settings:
Timeout 100
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 4
<IfModule Mpm_worker_module>
StartServers 10
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 1000
</ IfModule>
Compiled in modules:
core.c
mod_log_config.c
mod_logio.c
worker.c
http_core.c
mod_so.c
The following test results, which are very strange!

I noticed that in the apache error.log is a lot of entries:
[notice] mod_fcgid: call /www/XXXXX/public_html/forum/index.php with wrapper /www/php-fcgi-scripts/XXXXXX/php-fcgi-starter
What I have omitted, or do not understand?
Such a difference in requests per second? Is it possible? What could be the cause?
