RE: [PHP-DEV] PHP Performance in Apache: Multi-Process vs Multi-Threaded

This is just personal experience and observation but... We are running Apache Worker with PHP safely by using PHP-FPM rather than via a shared object, so we don't have to worry about thread safety in the PHP component but can have apache multithreaded. I realise this isn't actually multi-threaded PHP but multi-process instead but s means we don't have to worry about making sure extensions etc are thread safe. I haven't got the benchmarks to hand but I might able to dig some of them out if you would like. Apache Worker + FPM was definitely faster when using some simple PHP scripts to test against. Oddly we haven't noticed such a speed increase when benchmarking a Zend Framework based app, but that might be down to application oddities rather than anything else (more work/investigation needed here!). Hope this is helpful. James
