I am thinking of switching from the non threaded prefork mpm to the hybrid multi-process multi-threaded worker mpm for apache (2.0.52).
It runs on a Intel(R) Xeon(TM) Quad core machine running RHEL4.
I heard the worker mpm scales better and we have been having some scaling issues recently.
/usr/sbin/httpd -l mentions prefork as the compiled in mpm. what is the best possible way to switch to the worker mpm without changing any config ? i want to avoid building from source. is there a place where i can find rpms for apache compiled with worker mpm ?
I use apache for a) blog(wordpress) b) forum(phpbb) c) serving static content for a java web app (uses mod_jk to forward dynamic requests to tomcat )
what could be the possible issues that i need to consider before i make the move ? Also, what are the typical performance improvements after switching to worker mpm ?
