Strange, that's not what you should expect. Disabling tso and gso will retrun full speed on interface, because latencies is added in the driver patch when using segmentation offload on intel ethernet card.

Another try: https://pve.proxmox.com/pipermail/pve-devel/2019-December/040999.html The patches have been sent to the pve-devel mailing list and are likely to be integrated into the main code in the near future

I'm on a 5.X-kernel too, udp buffer overrun was fixed in e1000 driver in 4.15 kernel while caused segmentaion offload limitations, so you should turn off it if you want full speed. Did you try solution before writing answer? For me disabling in driver tcp segmentation offload (tso) and generic...

Maybe should try to disable tcp segmentation offload and generic segmentation offload ethtook -K <interface> tso off gso off There is known problem with Intel i218/i219 NIC and e1000e driver - buffer overrun while the I219 is processing DMA transactions. Problem was fixed in kernel 4.15...

I have a patched version that has been working on production for more than a year now, and a little over a month on PVE 6.0. I haven't had any problems with this particular patch so far, so I think it's quite reliable. You just need to remember to apply patches after each PVE update. (I have...

I've got 15k-16k random write IOPS in 16 threads with 4k blocks per bluestore OSD on 40G IB net, but that is the good result, 10k per OSD is not bad. With io-thread=1 I can get only 1400-1600 IOPS of random writes. The problem here is the OSD code latencies an WA produced on every operation. OSD...

I have this patches work on production more than 6 month for now without any cases, is there any reason why this patches is not merged to oficial code tree, maybe we can do something to speed up approval procedure?

Hello there, can anyone help to add this patch to PVE to configure MTU by Network Edit dialog There is only to patches First adds ability to specify in network config parameter ,mtu=MTU_NUM /etc/pve/qemu-server/VMID.conf --- /usr/share/perl5/PVE/QemuServer.pm.orig 2018-08-30...
