And let the great VM debate begin (again!) :P I've always ran game servers in some flavor of ESX/ESXi with 0 optimizations on the OS side. Ran just fine. Granted, I wasn't trying to load up a ton of VM's w/ game servers on 1 box ... but I've never had performance issues until the internet link got saturated (doh!). Karl Weckstrom ran a few TF2 servers and a website and other stuff all in ESXi with no problems, he's got a ton of info about it ... just gotta dig up his e-mail and ask away....

We actually see very good performance here with optimized (using PV or HVM w/stubdoms and GPLPV, with various kernel and configuration tweaks) Xen setups, to within a small percentage of bare-metal. What hypervisor technology and speeds of machines have you been testing with? Are you allocating dedicated HT cores to each guest? -John On 9/9/2011 12:11 PM, Darren M wrote: > 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.)
