title: Executing unit tests of Azure with a local storage emulator is very slow
body: <p>Me and some colleagues are facing some very annoying problems executing the unit tests of our Azure services. </p>
  
  <p>We have pretty nice workstations equipped with Xeon CPUs @2.67GHz, 6GB of RAM, and SSD disks. The strange thing is that for some of us the execution requires around 15 minutes, but one of us executes them in 2 minutes or so (and he has our same configuration machine). We weren't able to find out different configurations of SQL Express or of the Azure SDK installation.</p>
  
  <p>I don't know which details I can give you to explain better what it happens, if you have any suggestion to improve the question I'll be glad to edit it.</p>
  
  <p>Any ideas on what to check, change, try?</p>
