Hi, Looking for recommendations.I need to serve 100-200+ concurrent users to provide php based webmail client (horde). I have setup memcached and php-fastcgid for this purpose. The server has four 2.2G AMD optereon cores with 8GB of memory. I am doing stress test using ab as: ab -t 36000 -c 100 https://url/h/imp/login.php. What I have noticed if the number of concurrent users are more than around 25, I get the sluggish performance and I can see linux load rising high to 25 to 30 and all the cpu cores are approximately 75% used.This is what I have in config files: mpm worker: -- <IfModule worker.c> StartServers 15 MaxClients 960 MinSpareThreads 75 MaxSpareThreads 150 ThreadsPerChild 64 MaxRequestsPerChild 5000 -- memcached: 4GB --- fcgid: <IfModule !mod_fastcgi.c> AddHandler fcgid-script .fcgi MaxRequestsPerProcess 10000 MaxProcessCount 100 IPCCommTimeout 240 IdleTimeout 240 ProcessLifeTime 300 BusyTimeout 300 DefaultMaxClassProcessCount 100 DefaultMinClassProcessCount 50 </IfModule> --- php-fcgid:# Number of PHP childs that will be launched. Leave undefined to let PHP decide.# DefaultInitEnv PHP_FCGI_CHILDREN 4 # Maximum requests before a process is stopped and a new one is launched DefaultInitEnv PHP_FCGI_MAX_REQUESTS 10000 ---- OS: RHEL 5.5 Apache: 2.2.3 PHP: 5.1 Mysql: 5.0 Will appreciate for any inputs. Thanks! Paras.
