In my last post I wrote about some problems that I had with my virtual server that freezes under heavy load. The improvements I suggested worked really nice but the server still sometimes freezes – not often as before but it still happened. So I “googled” around and also asked at ServerFault.com.

It seems that keeping up the the apache mpm_prefork and mod_php will not be the solution anymore. Most sites suggested to use mpm_worker instead, because it uses less memory (and my problem was, that my Apache consumed all my memory). On the other hand there could be some problems with thread-safety, but I liked to give it a try. PHP will not me used as an Apache module any more.

PHP is not the fastest scripting language, that truly a fact. Except from optimizing the scripts there a few possibilities to speed everything up. One is to install a byte code optimizer and cache on your server. They cache the byte code created by the PHP parser and try to optimise it. So every time some one requests for a page on your server the script does not have to be parsed again. This brings a speedup of 120 – 250% depending on you script. There are several byte code caching program available, the one I like most is eAccelerator. Sadly eAccelerator is not available through the Ubuntu repositories so you have install them yourself. Here is a short description how to archive this!
