Hello devonblzx:

1. Can you attach your:

1.1. /proc/cpuinfo
1.2. 'ps -ax' output before you start the unixbench test on CENTos kernel and on OVZ kernel also. Are you sure there are no other running processes while unixbench is running? I think it's better to run "/sbin/init 1" before start tests.

2. Can you also set "maxcpus=2" kernel command line option for OVZ kernel and rerun tests again? Then you can try "maxcpus=1".

We need some information to investigate this issue. It can be SMP-scalability problem and it can depends on your CPU's hardware topology.
