When I was on the hunt for the fastest most productive way to fold in windows, I ran across VMware. At the time I was running Win SMP. My CPU was running at 3.2Ghz I believe, and was getting 12 minutes per %. When I ran VMware + Ubuntu, I couldn't believe my eyes, my times were now 9 minutes per %. VMware had shaved 3 minutes per % off my times.
