This was initially my setup. I thought that maybe there's an issue with the
windows release (because I know it didn't use to be fully supported). That
was the reason I've tried to setup the Ubuntu VirtualBox machine to test the
performance. In both scenarios I get the same results. I can only imagine
there is a problem somewhere - either in the configuration or something more
subtle and I cannot identify it.

virtualization as a potential culprit.
