Visual studio 2012 slow unit testing

Question

Running unit tests on VS2012 is lately very slow, when I run them it takes about 12 seconds before they start actually testing.

When I debug it is the same story bef

Answer 1

Visual Studio update 1 is now available and apparently addresses some speed issues with unit testing, whether it's related to Mailslot or not I don't know but presumably that's possible if it's in use as a communication mechanism by mstest somehow, from the MSDN forums:

In the upcoming Visual Studio quarterly release (ref http://blogs.msdn.com/b/visualstudioalm/archive/2012/10/08/visual-studio-2012-update-1-ctp.aspx), we have made some performance improvements. In short, we changed the underlying storage mechanism to improve the discovery/run time.
