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.
Recently, I ran tests against my Windows development VM running on a new late 2013 Mac Book Pro (2.6Ghz I7 Haswell with 1TB PCIe flash storage). The scores:
PassMark Overall: 3424(33.91% improvement)
PassMark DiskMark Overall: 4080 (40.20% improvement)
Build/Test Large .NET App: 3:29 (16.4% improvement)
The bulk of the improvement comes courtesy of the lighting fast PCIe flash drive in the new Mac Book Pro.
I’ve posted a complete list of results on Google Docs.
