I have a new two Intel Server ( SC5600BRP, S5520HCT, E5645, 4xSAS RS2BL040 RAID 10, 2008 R2 x64 SP1).
When you install Hyper-V network performance drops by about 40 - 50%The same network on the older server with the hyper-v role I have twice the bandwidth of the network. Ideas from google or special fixes microsoft does not help.
Thanks but it did not help.
Two serwers with 24GB RAM
cpu E5645 - network bandwitch 55MB/s
cpu E5606 - network bandwitch 95MB/s
no Hyper-V - network bandwitch 120MB/s
