Prefork vs Worker MPM in Apache
« on: November 14, 2005, 11:48:22 AM »
I am a little unclear as to the exact difference here and how these are used by the server.  I see that most of my Apache config files ( /etc/httpd/conf/httpd.conf ) have both prefork and worker MPM settings included.  Does anyone know if Apache uses both of these or does it choose one over the other?  How does it/you choose?

Prefork vs Worker MPM in Apache

Prefork MPM takes an Apache process and forks it into multiple identical processes, whereas Worker MPM creates multiple unique processes.  In systems with 1 or 2 CPU processors, prefork is the preferred method since time is saved having the processes be more related.
