Was there any info on how OpenVZ was setup or how many other
containers were running on the machine, Do we know what the load was
on the machine at each stage of the tests?  We really do not know
anything.  The web servers were not even setup the same.  The hosting
outfit could see a system spike and automatically kick in a limit that
we do not know about. I do that all the time. That is a common
practice.  If you do not control the system, you cannot do a valid
