Hi openwrt users,
I've acquired a pair of banana rpi4 routers and installed latest openwrt available. (openwrt 25.12.4)
There are a few tips on its wiki page, which I've followed, namely the hardware offload and installing irqbalance.
I've then set up the wan interfaces as static IPs and ran iperf3 towards the other interface but speed is always under 5gbit/sec. (a cisco sfp+ and a mmf fiber is used on each wan port)
For the sake of testing, I've tried disabling the firewall, but same results are achieved.
I'd appreciate any other tips/suggestions/rtfm that may help improving this.
Best regards
