24.7 Production Series / Re: HELP NEEDED: Performance issue on DEC850 after upgrade to 24.7

« on: November 14, 2024, 12:29:05 am »

I've noticed a bizarre behavior (DEC3840 here)...

All HW offload is ON but VLAN.

By bringing down and then back up ax0 via ifconfig, I achieve clean 9.4G UP/DOWN

If I reboot, I need to run that command through shell again otherwise I'm capped to 4.5G UP/DOWN

Just upgraded my Qotom Q20332G9-S10 (Intel Atom C3758) running Proxmox 7.4 from 24.1 to 24.7 and noticed I wasn't getting 2.5G line speed as before.

Also had 100% CPU saturation during iperf and speedtests.

Tried `ifconfig <ix> down && ifconfig <ix> up` on the LAN and WAN interfaces and I get (mostly) expected line speed. Seemed to be stuck on 1G speeds beforehand, even though ifconfig reported 10Gbase was autonegotiated.
