php-fpm is a separate service from apache httpd. Requests are proxied 
from Apache httpd to php-fpm. So while it doesn't matter which MPM 
you're running on the front-end server (or, indeed, if you're running 
Apache httpd at all), we do rather strongly recommend that you 1) 
upgrade to 2.4 if at all possible, and 2) don't use prefork unless 
there's some compelling reason to do so. In the old days, the compelling 
reason to use prefork was that you were using it in conjunction with 
mod_php, which had possible threading problems (to oversimplify). If 
you're using php-fpm instead of using mod_php, then there's really no 
reason any more to use prefork.
