MS-01 performance issues w/ Intel 226 NICs
-
Anyone else seeing Intel 226 (I226-LM / I226-V) network performance issues? It seems the receive performance is fine, but transmission speeds seem kneecapped at 200Mb speeds on a Gigabit switch.
My old 2012 MacMini's running XCPNG are able to migrate VM's in 1/4 - 1/2 the time that it takes my new MS-01's between nodes.
I see the same thing on XCP-NG 8.2.1 and 8.3 beta 2.

This is probably the same issue as I see on my NUC11 and NUC13.
Try turning off ASPM in the BIOS and see if you still have the same issue.

@xerxist It's good you commented. I finally figured this out and had intended to come back to update this post but forgot. Yes, that was the magic secret that solved it all.
Now, if only we could get Thunderbolt Networking support in XCP-NG, it would be perfect, but I can imagine that's not a high priority for the Vates team.
None the less, my 3 X MS-01 cluster (not setup as a pool.... yet) continues to work very well for it's first month in service.

Good stuff
I wish I could use it but still waiting for them to start using a new kernel. As on the NUC13 I can’t use my igpu for passthrough on an old kernel. Need something above 5.15

@cowboy Did you use
pcie_aspm=offin GRUB or disable it in the BIOS? -
BIOS but if you dont have to option there you could use that.
-
@xerxist If you have time to test options, it would be interesting to see if other choices fix the problem (disable and off should be the same).
pcie_aspm=disable pcie_aspm=off pcie_aspm.policy=performance -
@Andrew I flipped it off in BIOS, worked like a charm. BTW, I'm only on a 1G switch with my 226's. Looking forward to getting a faster network switching at home now.
Looking forward to eventually test driving XOSTOR on this cluster.

I’m good with the BIOS setting for my NUC11 and 13. I wish Intel would fix ASPM, but still not on the latest BIOS. Just can’t run xcp-ng yet because of the older kernel and passthrough issue on the NUC13.
It will probably come soon as 4.19 is out of support pretty soon. Was actually hoping there would be a alternate kernel for testing already.
