For years I have been using the mpm-prefork module as it was my understanding that this was the preferred worker for Apache 2 and 1.3.
Now I will be installing some fresh Apache servers and will be using the newer 2.4 version, with which the event based mpm which uses epoll/kqueue.
I know in the last few years event based systems have become all the rage (e.g. nginx, lighttpd, node.js), so since mpm-event is now stable in Apache, is this the preferred multi-processing module to use?
I also took note of the comment from the mpm-event documentation page:
The improved connection handling does not yet work for certain connection filters, in particular SSL. For SSL connections, this MPM will fall back to the behaviour of the worker MPM and reserve one worker thread per connection.
Our main site forces an SSL connection, so it is clear that we will not benefit from the improved connection handling related to keep-alive, but is my understanding correct that there will still be some performance improvement since there will be less threading taking place?
