Mike Walsh shares some advice:
If you’ve ever asked yourself, “Why does my SQL Server seem slower on Hyper-V than it should be?!”, this post might help. And if you asked me about Hyper-V ten years ago, I’d probably have laughed. Maybe even less than that. But here’s the thing: it scales, it works, and with the Broadcom/VMware “fun” squeezing the world for profit, we’re seeing more and more folks making the move to Hyper-V. You have to pay attention to some key configurations, just as with VMware..
None of this is radical advice, but it is good to make sure that you have the basics covered because these can make a difference.
