Thread:Project:Support desk/Is MediaWiki CPU intensive?

Hi! I want to run a MediaWiki website and was wondering if MediaWiki was more CPU-intensive or RAM-intensive? By that I mean when I'm selecting a VPS, should I be looking for ones with more RAM or ones with multiple-CPU-cores and better CPUs? Is MediaWiki capable of running multithreaded - i.e. would a KVM VPS with a higher single thread performance be better or would a OpenVZ VPS with 4 shared cores (and thus multithreading capable) be better? Thanks!
