Thread 'iperf3 retries on VMs'

Jan 8, 2025

I am running a PVE cluster (3) on 6.8.12-4. I have a Dell R730XD, and 2 R630s. 2 boxes have the Intel(R) 10GbE 4P X710 rNDC, and the other has the BRCM 10G/GbE 2+2P 57800 rNDC. iperf3 runs great between my NAS and PVE hosts (and their containers), but not on the VMs runnings on those hosts. The throughput is good, but as you can see, the retries are through the roof!

Any ideas???

Performance between the NAS (10.0.1.100) and a PVE host (apollo - 10.0.1.102) is great.



Performance between the PVE host (apollo - 10.0.1.102) and a VM (prod-plex - 10.0.1.105) is great...

I need some help! Does anyone have some ideas on why this would happen?
