There have been a lot of posts on the internet discussing VMQ’s. Microsoft had published this LINK to ensure that the best performance was experienced on Virtual machines. VMQ is supposed to offer an intelligent buffer, whereby virtual machines benefit from network cards which can offload and prioritise virtual machine traffic. The fact is that the Broadcom cards cause high latency issues, and inconsistency with network traffic.
I tried a few tests:
1.5 GB file:
I tried a few tests:
1.5 GB file:
- Copying from Physical Machine to Physical Machine: <10 seconds
- Copying from Virtual machine to Physical Machine: 34 Seconds
- Copying from Virtual to Virtual machine: >1 minute
Once this was completed then performance of the virtual machines suddenly increased. They are now running as fast as the Physical ones. However more performance gains were found when moving to Intel cards and the network traffic was very stable.
So I took the time to upgrade the servers to Intel cards and now everything works pefectly
