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

I had the same issue, using VS2012 Update 1. Based on the suggestion in http://social.technet.microsoft.com/Forums/en-US/winserverDS/thread/20eb50e9-3e68-4d29-bcdd-a4fc166b9c00 I disabled NetBios over TCP on my NIC. The tests now start up immediately, and procmon shows the time waiting on \MACHINE*\MAILSLOT\NET\NETLOGON dropped from 5 seconds to about 40 microseconds.
