Ah, I came across this link. I think there were some issues with the 
particular release of OpenVZ they used (based on forum postings). Also, 
it seems to have more restrictive defaults for a new VM. With my 
testing, I was seeing vserver with ~ 10% gain, although that was in a 
cpu+network limited scenario with no real tuning to either setup.
