Apache prefork vs. worker

WORKER Is Better than PREFORK

Prefork is supposed to generally be better for single or dual cpu systems, and worker is supposed to be generally better for multi-CPU systems

IfModule mpm_prefork_module
————————–

StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0

IfModule mpm_worker_module
—————————

StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0


PHP5 can work with MPM Worker too. But you have to use CGI or FastCGI instead of Apache module
