I really appreciate the Hyper-V performance, as well as the modularity of the operating system: it’s easy to turn piecesenCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/bobgerman/archive/2008/09/17/the-compleat-windows-server-2008-laptop.aspx#8954871Wed, 17 Sep 2008 08:00:56 GMT91d46819-8472-40ad-a661-2c78acb4018c:8954871Kris<p>How is the performance? I am planning to do the same but am worried about the performance for doing demos with Biztalk, Sharepoint. </p>http://blogs.msdn.com/bobgerman/archive/2008/09/17/the-compleat-windows-server-2008-laptop.aspx#8955723Wed, 17 Sep 2008 19:09:25 GMT91d46819-8472-40ad-a661-2c78acb4018c:8955723BobGerman<p>I actually set this up on two machines. The one where I enabled all these desktop features is only marginally faster than it was using Vista with Virtual Server 2005... no such thing as a free lunch I suppose! The other one I only enabled Hyper-V and left off all the other stuff and it seems MUCH faster, almost as if it's running directly on the metal (which may be close to true in Hyper-V!) I'm considering setting up a dual-boot on my every-day laptop so I can boot it as a desktop w/slow virtualization or a server w/fast virtualization.</p> <p>Remember that memory and disk speeds make a huge difference! Putting the snapshot directory on a different spindle is also helpful if you can swing it.</p> <p>Also note that with Hyper-V you can run multiple CPU's (or cores) in a guest VM, which should help if you're not disk bound ... and also you can run 64-bit guests, which will become increasingly important as server products move in that direction.</p> <p>That said, it would be interesting to do some real performance testing; so far I've only got empirical evidence.</p>
