[SOLVED] Network performance degradation

For a couple of days I noticed a huge degradation on my network servers, specially on Jellyfin. I lagged a lot, and I needed to transcode the stream for it to work (with a huge quality loss). I was quite baffled about it and search thru my system to any obvious flaws, but cutldn't find anything out of the usual. Normal downloads seemed to work with satisfactory speeds, but still I seemed like I has maple syrup in my system. After going thru my logs I could find this; enp1s0: bad gso: type: 1, size: 1460.

After searing for this error, I found bug 219129 in kernel.org (https://bugzilla.kernel.org/show_bug.cgi?id=219129). It talks about virtio net performance degradation between Windows and Linux, but it seems to affect Linux performance in general. A fix seems to be on it's way

If you find the network to be laggy (at least for virtio), this is probably the cause of it. Downgrading solved it for me for the time being.

Yeah at this point it's just a matter of waiting, the patch already is in the stable queue: https://git.kernel.org/pub/scm/linux/ke … _hdr.patch
