I have a symmetric 1Gbps FTTH connection, and I just replaced the ISP provided router with this mikrotik and openwrt. After enabling hardware offload, I was able to get 1Gbps download, but below 300Mbps upload.
When testing bufferbloat, latency spikes a bit more on the upload test as well (about 50ms).
I tried disabling IPv6 because of this thread, which I don't understand completely, but it didn't help.
Any pointers? Should I share any logs or config? I'm on 22.03.0-rc4.
