Hello all, I want to know how much Apache's HTTPD takes the advantages of multiple CPUs. Is there any difference about performance betwen using worker or prefork as MPM?? Being a little "out of topic", let me ask you... On a Linux SMP system, does a n Core processor works like n processors?? Is there any differences taking performance advantages of multiple CPUs betwen using multiple threads or multiple processes?? Just to make you understand the issue, I'm want to setup a dedicated web server with two Quad Core processors, and I can't use worker(which is multi-threaded) because I'm using mod_php. So, what I really want to know: it's a fact that many CPU's(2 processors x 4 cores = 8) will improve the processing performance??
