Blue Probe It’s the parting gift when you host an alien abduction

I read Encyclopedia Brown books when I was a kid.  At the end of each story, the mystery was wrapped up nicely and each piece of the puzzle explained.  This is not one of those stories.

While using VSTS for Testers, I discovered that 2 of the 10 VM's we had serving an ASP.NET application ran about 1/10 as fast as the others.  Hmmm.  Both were on one physical host.  So here is what we did:

We moved a good server to the “bad VM host” and it still performed well.  Then we moved one of the two bad servers to a “good VM host” and it started performing well.  So we decided to test the second bad server again which still remained on the “bad host” and it started performing well.

We used to pull a trick on newbies telling them to press <ctrl>+<up arrow> to increase system speed.  But that was just a joke - right?
