I've noticed on cPGS users' machines that VMs / VPS of all flavors really struggle when it comes to running game servers well, even with a VM given 100% of all the resources of the dedicated box (for testing.) I strongly suggest to our users to save the VPS/VMs for mail or NS and let the game boxes be dedicated. Nothing taxes hardware in quite the same way that is also as prefectly monitored by so many people at the same time as game servers ^_^
