Apache2 using prefork MPM, is worker possible? We are running several ISPConfig 3 servers over OpenVZ for our clients. We create the servers based on the "Perfect Server for Ubuntu 10.04" howto. We noticed that ISPConfig based mod_php servers use a HUGE amount of memory. When checking, we found it's prefork MPM that's being used: Code: [email protected]:~# apache2 -l Compiled in modules: core.c mod_log_config.c mod_logio.c prefork.c http_core.c mod_so.c Is it possible to use the much more memory-efficient worker MPM with ISPConfig and mod_php and/or fcgi?
