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?

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 eva= luate performance gain.

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