Late last year my colleagues and I tried to distil the tasks that impede SharePoint developer productivity. Then I ran those tests on EC2, Hyper-V and VMware Workstation, with the latter two virtualisation technologies running on a desktop, an older laptop and a newer laptop. In this post I hope to shed a bit of light on some follow-up testing that I’ve squeezed in to the odd hour here and there over the last six months. Unfortunately hardware availability and my schedule have not aligned to produce a further round of comprehensive tests and since I can’t see that occurring in the immediate future I’m going to fill in some gaps here with a couple of additional concrete findings, particularly regarding i5 vs. i7 testing and the impact of SSD on first page load times after application pool recycles. I’ll also talk less rigorously about a few related issues.

The Core i7 processors feature the Nehalem processor microarchitecture, which means that Hyper-V V2 (in Windows Server 2008 R2) can take advantage of SLAT (Second Level Address Translation). SLAT is implemented as EPT (Extended Paging Tables) in Intel technology and NPT (Nested Paging Tables) for AMD. Here’s Microsoft’s summary of the new Hyper-V support for SLAT: Continue reading “Hyper-V graphics performance is on the way… if you need a new laptop”
