Quick aside: does ESXi still impose too much overhead to move a compile farm onto VMs?
A friend of mine tested it 3 years ago and it was something like 300% slower (no idea about the disk config, but he's a smart guy). It would have been worth it at anything under about a %50 hit...
We tested it at my last job maybe 5 months ago and it was a complete failure. Granted we didn't spend a lot of cycles on it, but we saw how slow it was and went back to native hardware pretty quick.
Two reasons:
- Easy migration between hardware configurations of a running system.
- Snapshots to revert quicker after a failed upgrade / change. (Typically in addition to traditional backups.)
