Since we published an initial support and guidance statement for deploying Office SharePoint Server on Hyper-V (Using SharePoint Products and Technologies in a Hyper-V virtual environment), a series of tests were run to measure Office SharePoint Server performance on virtual servers.
These tests collected performance data from small and medium farm configurations deployed on:
Hyper-V virtual servers
Detailed information about our performance tests, results, comparative analysis, and configuration recommendations are documented in Performance and capacity requirements for Hyper-V, which is now available on TechNet.
If you are considering deploying SharePoint on Hyper-V, or have already done so, this article is a valuable "must read". As always, your feedback is greatly appreciated.
