I have Banana Pi R2 PRO router and installed OpenWRT (Linux OpenWrt 6.6.43 #0 SMP Sat Jul 27). Im testing routing performance using open speedtest server installed on the router (docker) from my lan.
I was very surprised by getting very poor download performance, around 20Mbps over 1Gbit ethernet. What is strange the upload speed is normal around 900Mbps.
Ive enabled Software flow offloading in Firewall setting, but it does not help much. Is there anything more I need to do to fix the performance issues?
I tested couple of recent OpenWRT release (kernel: 6.6.43, 6.1.94) using default settings. Always the performance is disappointing.
It could be that kernel is quite new. I took one of the release from Releases · mj22226/openwrt · GitHub.
If you know a stable release which works fine please advise.
