I configured sqm to have 800 megabit/s each direction, and ran iperf3 over IPv4 with NAT44 from Linux box behind WRT1200AC to an OSX macbook connected on a switch on the same L2 subnet as the WAN port. Linux <->WRT1200AC<->switch<->OSX I get 765 megabit/s of throughput using single session, at sirq load of around 25%. If I lower the mss to 300 (to generate higher pps) I get around 560 megabit/s of throughput at 50% sirq. With 10 parallel TCP sessions, I get about the same. At MSS of 200 bytes, I get 400 megabit/s at 70% sirq. If I turn off SQM completely, I get 600 megabit/s at 200 byte MSS single session at 80% sirq and 930 megabit/s at 26% sirq with default MSS. So if you want high performing device that is OpenWRT compatible and still does forwarding using CPU so you can test queuing algorithms, the WRT1200AC and WRT1900ACv2 is the best I have been able to find currently (unless you go for x86 platform). -- Mikael Abrahamsson email: swmike@swm.pp.se _______________________________________________ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel
