hello,Elena,

I have implemented the vNUMA for HVM guest,I use the NPB(OMP and MPI) benchmark to test the performance,but no improvement.Howerver,VMWare declares that the vNUMA Can greatly enhance the performance of 30%,why?

And about your vNUMA for guest?

Hi Butine.

At the moment I did not perform that kind of evaluation and as soon the
major issues will be resolved that will be the next step to evaluate
performance gain.

Though in general I would like to see how VMware evaluated the performance
gain in 30% and what applications they were using for such tests. I think
the results may vary pretty dramatically in regards to workload type.
Do you have any more information in this?
