OpenWrt has backported Netfilter's flow offload functionality from kernel 4.17 to 4.14. I've been noticing higher speeds as well as higher latency with it enabled. Anyone have any insight? My test results are here: On: http://www.dslreports.com/speedtest/37007587 Off: http://www.dslreports.com/speedtest/37007494 Note the latencies.
