Inconsistent performance on E810 with SuperMicro server

[chuff]

We've recently purchased some SuperMicro servers with the Intel E810 network card and getting very spotty performance when using a 25Gb SFP.      iperf testing on idle systems would seem fine but then crash to sub-gb/s for hours, only to recover later.     We have put 10G SFP in place that seems to keep things at 10Gb/s but not having 25Gb performance seems like a waste.  

I'm working through the performance tuning guide but wondering if there are any other settings we should be looking at.   Opening a ticket with Intel or SuperMicro?  

Our fleet has the following config:

System: SuperMicro

Model: AS -2125HS-TNR

CPU: AMD EPYC 9534 64-Core  (2)

RAM: 1.5TB

DISK: (full load) 24*8TB nvme

NIC: E810  (E810-XXVDA2)  

NIC NVM: 4.40

NIC driver: 1.13.7

OS: Ubuntu 20/22
