Performance extremely slow on ER-X with hw offload enabled #62

Open eng3 opened 3 years ago

eng3 commented 3 years ago

Using ER-X. When hw offload is enabled (to achieve gigabit network speeds internally), wireguard traffic is extremely slow (< 500 KBps) and unreliable. When hw offload is disabled, wireguard traffic is normal (> 1 MB/s) (however internal network speeds are 1/3)

I would think hw offload should speed up things, not slow it down

I was hoping 2.0.9 would solve it as it had a bunch of HW offloading fixes https://dl.ubnt.com/firmwares/edgemax/v2.0.9/changenotes-v2.0.9.txt but unfortunately not...
