Subject: [Intel-wired-lan] Supermicro AOC-STGN-I1S (Intel 82599EN based 10G adapter) - poor network perfomance after moving to Debian 11.5
Date: Sat, 14 Jan 2023 11:23:01 +0100	[thread overview]

Hi

After moving from Debian 9.7 to 11.5 as soon as I perform "ip link set 
enp1s0 up" for my 10G adapter (AOC-STGN-I1S - Intel 82599EN based 10G 
adapter) I am experiencing high cpu load (even if no traffic is passing 
through the adapter) and network performance is low (when network is 
connected). The cpu load is oscilationg between 0.1 and 0.3 on vanilla 
system with no network attached. The problem can be observed on the 
following platforms: Supermicro X9SCL (Intel C202 PCH) and Supermicro 
X10SLL+-F (Intel C222 Express PCH), but for the Supermicro X11SSL-F 
(Intel® C232 chipset) everyting is working well.

Tested enviroments:
Debian 9.7 - Linux 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 
(2018-05-07) x86_64 GNU/Linux [all platforms working well with no 
problems: Supermicro X9SCL (Intel C202 PCH), Supermicro X10SLL+-F (Intel 
C222 Express PCH), Supermicro X11SSL-F (Intel® C232 chipset)]
Debian 11.5 - Linux 5.10.0-19-amd64 #1 SMP Debian 5.10.149-2 
(2022-10-21) x86_64 GNU/Linux  [older platforms: Supermicro X9SCL (Intel 
C202 PCH), Supermicro X10SLL+-F (Intel C222 Express PCH) behave 
problematic as described above | newer platform: Supermicro X11SSL-F 
(Intel® C232 chipset) working well with no problems]

So far to solve the problem I was trying to upgrade system to the newest 
stable version, upgrade kernel to version 6.x, upgrade ixgbe driver to 
the newest version but with no luck.

Supermicro support suggested as follows:
it might be kernel releted debian 11.5 has kernel 5.10 whihch is a 
recent kernel it might not properly support the chipsets for X9 
therefore i suggest to use RHEL or CentOS as they use much older kernel 
versions. I expect that with ubuntu 20.04 you see the same problem it 
uses kernel 5.4

Best regards
