Basically, PreFork is the old MPM from Apache 1.3 series and forks one process for each new request. Worker is a multithreaded module. It will launch multiple threads to service new requests. Apache 2.0 has other multithreaded MPMs, like ThreadPool, PerChild, Leader (what happened to these in Apache 2.2?). Worker is more efficient on the resources and faster. PreFork is "old school". One word of warning. If you are running PHP on that Aapche, you will be forced to use PreFork, since PHP doesn't guarantee thread safety. Don't misunderstand me, PHP5 core IS thread-safe, most of the PHP extensions ARE thread-safe, but most of the 3rd party libraries, used by those extensions ARE NOT. Therefore, RPM install or YAST will set MPM to prefork if you load mod_php. Nix. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
