Over on Todd Baginski’s blog, he recently conducted a thorough comparison of using Microsoft’s Virtual Server 2005 R2 vs. VMWare’s VMServer 1.01 product for MOSS 2007 development. The results were surprising, with VMWare winning on common tasks by a total of 38%. Since both products are free at this time, it seems that VMWare’s solution is the way to go right now. I shouldn’t be as surprised, since VMWare has been in the virtualization game for a long time, but the time differences are amazing nonetheless.
