Here is a quick tip from Aaron Silber :
I was meaning to send this out a little while ago, but never got around to it. I ran into an issue where you click the AMC, or Delivery Services Console as it is now called and it can literally take upwards of five minutes before it even launches, I was pulling my hair out (ok, the little I have left!), but finally found the answer. All you need to do it create a mmc.exe.config file in the Windows\System32 folder and in it place the following:
<?xml version="1.0" encoding="utf-8"?>
<generatePublisherEvidence enabled="false" />
Save the file and try to launch again, presto! From what I understand there is some sort of signature checking that .NET does which can be quite intensive, this disables it for the mmc.exe process.
