I am running Windows 8.1 with Visual Studio 2013 and .NET Framework 4.5.1 in a Parallels VM under OS/X Mavericks on a 2012 Mac Book Pro. I will be doing some things with the hardware, OS and system configuration to speed things up.
This morning, I upgraded to the latest version of Parallels Desktop, 9.0.23140. My current scores:
PassMark Overall: 2813 (10.01% improvement so far)
PassMark DiskMark Overall: 4080 (2.46% improvement so far)
Build/Test Large .NET App: 4:07 (1.2% improvement so far)
I’ve posted a complete list of results on Google Docs.
