Lately I've been wondering this just as kind of an offhand thing. On average, how many VPSs can be made per physical CPU in a system? I do know the RAM and Hard Drive are also limiting factors, but someone recently told me that a single quad-core CPU would not be able to reliably support enough VPSs to actually use up much more than 16 GB of RAM, and a node with more than that should have more than one CPU in it. Anyone here with some experience designing VPS nodes that they'd be willing to share? I already know to provision with lots of ram, and plan on at least RAID1 but preferrably RAID5 for storage. But this CPU thing bothers me, because you can't just break down the assignments numerically like you can for RAM and Storage on a non-oversold setup.
