@jonp I can make a new thread if that is helpful, but I downgraded back to unraid 6.8.3 and results are confirmed to be what I expected. I did nothing else other than rollback via the GUI, then go to VMs and and I reselected a Q35 machine and boom, everything was fast again. (web vnc messed up but no big deal at the moment)

Yeah, I dont think it has anything to do with the 10gbe interface. I'm pretty new to virtualization and was banging my head on why the guest/host speeds are so slow and ended up traversing irrelevant things out of desparation! As far as the mikrotik, nothing is hitting the switch which is expected when looking at the data during transfers.

I set up a Ubuntu VM pretty quick and getting similar results. I could try reinstalling unraid back to the stable version to verify that everything was fast af. I was just having some issues with creating VMs with my hardware setup and the upgrade seemed to make things much smoother.

Yeah, so I'm getting proportions similar to iperf when transferring files to shares. Also similar results on Blackmagic Disk Speed Test (primary use for one of my VMs will be video editing once this gets worked out!). I'm writing to a share that is only stored on cache on these tests. I'm pretty sure before I updated to the beta I was getting good speeds. I attached a photo I took to show my buddy how nuts this setup is with a pcie 4.0 nvme drive. I've made new VMs from scratch as well and still getting similar results.

Hi @jonp! Sorry for the slow reply! It was my first post so I wasn't sure when it'd get approved. My connection from my Macbook is using a thunderbolt 3 adapter from CableMatters. I attached a quick diagram showing the setup. My main issue is I'm confused why the gust connection to the host is so slow... significantly slower than the connection from my MBP to Unraid Server. I'm using the asus xg-c100c on the Unraid server and in the vm, I just set it up using the virtio-net driver. Also of note is I'm running Version: 6.9.0-beta29 of Unraid.

Any luck on this? I am having *very* similar issues. My iperf results from my macbook w/ 10gbe adapter is over 8Gb/s while from a Windows 10 vm doing an iperf test I'm getting results of 1.19 Gb/s. This is driving me crazy! :) I've been searching for over a day and I'm struggling, so any help would be appreciated! virtio drivers are installed on the VM.
