Who said Apache isn't capable of low response times?

It seems incapable of the lowest response times, which it seems like Google has. Forking a new process to handle a request incurs overhead. In my experience nginx, which keeps several worker processes open and processes requests asynchronously is much faster.

Apache has a prefork MPM procesas model that allows it to run in the same way.

I don't know much about it, but I would think that event based mpm would be the fastest.

Depends on what you need to do. Apache has it all:

http://httpd.apache.org/docs/2.4/mpm.html

http://httpd.apache.org/docs/2.4/mod/event.html

Yep that's what I meant. I believe event based would be faster than the prefork that pling suggested.

Apache does not fork a new process to handle a request. Not even in prefork mode.
