1: Does anyone know if VMplayer has a limited memory bandwidth, compared to the physical bandwidth in the host computer? Is there a bottleneck? I do BOINC crunching on VMplayer guests on two different physical computers, and when I do especially memory bandwidth intense work units, for CEP2, I don’t get any performance improvement on my faster computer, compared to the slower one. I’m thinking there perhaps is a limitation in the VMplayer’s memory bandwidth? 2: Does the guest OS have access to both physical memory channels, even if it only has access to 4GB of RAM, which is the amount I have in one of the two memory channels? 3: Also, I would like to know what the performance impact is from emulating virtual hardware and a guest OS? Thanks.
