Preface:
Please know that before creating this post I did my absolute best to not bother you fine folks with this request, scoured the forums, tried some fixes….then tried all the fixes and I am still at the same spot as I started
It should also be noted that I BARELY know what I am doing in comparison to a lot of you, so take that for what it is.
Problem:
I have very slow download with perfect upload speeds on both the host and client machines.
The same problem persists when a NIC is directly passed through to a client machine and is persistent across all VM’s regardless of OS
The host hardware was used previously with no issue
Steps taken so far with no improvement:
Verified full GbE connection between switch and host
Changed NIC and cables
Re-Install of PVE
Directly passed a wireless intel nic to multiple VM’s, same issue
Directly passed a Realtek wired nic to multiple VM’s, same issue
Changed MTU size (its back to 1500 now)
Added pre-up ethtool -K enp39s0 rx off tx off to network interfaces
Added processor.max_cstate=1 to grub
The last three were buried in some forum posts so I tried them.
I also have pasted below some information that was requested in other posts
I know it’s going to be something with the host machine, I just don’t know what…
Any help would be greatly appreciated as I really did try to learn and solve this on my own, however I just don’t think I am quite there yet.
TIA
