When you say that you have disabled VMQ on the adapter was that done for every Broadcom port being used by a Hyper-V vSwitch?

How is the disk subsystem set up?

Fixed or Dynamic VHDX Files on a shared partition or individual partitions?

Are the C states disabled in the BIOS?

Please see my E-E article here: Some Hyper-V Hardware and Software Best Practices.

I have Disabled VMQ on the Physical Adapter in Network Card Properties - Configure - Advanced and then Disabled Virtual Machine Queues.

I have also Un ticked Enable Virtual Machine Queue in the Properties of the Virtual Machine under Network Adapter - Hardware Acceleration.

I have 6 Disks on the Host the OS is two Disks Mirrored, and the other 4 Disks are Raid 10

I have also noticed that when I restart the file server everything is speedy then about 2 mins after restart it goes back to being slow again
Veeam Task Manager for Hyper-V

Task Manager for Hyper-V provides critical information that allows you to monitor Hyper-V performance by displaying real-time views of CPU and memory at the individual VM-level, so you can quickly identify which VMs are using host resources.

What is the RAID setup? Hardware RAID or software RAID?

Drive type? SAS, SATA, 10K or other?

Did you try changing the port on the physical switch where the host adapter is connected to?

Do you have teaming or it's a single adapter?

If you have another virtual machine connected to the same virtual switch: how about running some tests from there - is it slow as well?

Where was the A/V installed to be causing the problem?

On the File Server itself

Okay. Thanks for answering.

As a rule we put A/V on endpoints only. We do not install A/V clients on servers or virtualization hosts. That turns into a bear to manage for exclusions, but also drags down the servers themselves.

Folks should not be browsing or running e-mail from a server, all risky behaviours, anyway. It's the endpoints that work with the data so they are where we put the A/V client.
