What I find odd is that you switched two software packages and assume 
its apache's fault for the performance drop.  If you are just testing 
php code, it could very well be the php5 is slower than php4 for your 
code. 

 From my understanding prefork is recommended with mod anything in 
apache 2 right now simply because most modules link with non thread safe 
libraries.
