Well, but using something like eAccelerator should compensate this, shouldn't it? As far as I understand, scripts are being compiled and then store in memory to access them faster. >> I already installed an php-accelerator (eAccelator) which increased the >> overall performance, but still the performance is quite poor. > > I would not say php performace is poor, I think it is quite fast (at > least on my linux boxes, I know nothing about php on windows...) Well ... I did some stress-testing. I create 20 concurrent requests to my application: random pages, randomizing the post parameter, which causes to load different data from the database (MySQL 5.0.37, running on a separate server). My webserver is the same for java and php. Running my test for about 5 minutes, I get about 31.000 request for the java application, but only about 3.000 for the php. -- ...
