The test was on 32 core (model: Intel(R) Xeon(R) CPU X7560) HT disabled
with 32 KVM guest vcpu 8GB RAM.
Have you ever tried to get results with HT enabled?
I have not done it yet with the latest. I will get that result.

This looks good. Are your ebizzy results consistent run to run
though?
yes.. ebizzy looked more consistent.

Hmm, I wonder what 2.5x looks like. Also, the 3% improvement with
no overcommit is interesting. What's happening there? It makes

I 'll try to get 0.5x and 2.5x run for dbench.
thanks,
