I recently put Windows 8.1 Pro on my mid 2012 MBP 15". It has 16 MB RAM and a Crucial M500 SSD. Yet it boots slower than a similar Window 8.1 Pro installation running under Parallels Desktop 9. It boots slower than Mavericks 10.9.1. Even the Chrome browser logs before loading. Yet I am able to do some very CPU/disk intensive stuff, such as an ASP.NET based CMS, Sitefinity, that I've seen bring other development boxes to their knees. Doubt I could do that in my PD9 VM! Any ideas?
