Are there additional knobs for performance nuts?
We are trying to make Hyper-V knob-less. However we are engineers and here are some tips. 1. Remove the CDROM drive from the guest if you don’t need it 2. Look into the Caps / Weights / Reserves in the CPU config. You can use these to “balance” workloads. 3. You can use the WMI interfaces to force a VM to a particular node (http://blogs.msdn.com/tvoellm/archive/2008/09/28/Looking-for-that-last-once-of-performance_3F00_-Then-try-affinitizing-your-VM-to-a-NUMA-node-.aspx) Hyper-V does not guarantee node affinity for VP’s but it does for memory. There is a good chance the VP’s will stay on the node because the scheduler is NUMA aware.
