A) I bricked the archer c7 v2. No idea why. B) I got a sorta working linksys 1200ac build. The bad news: Any attempt to run 2 or more copies of netperf's netserver on the 1200ac router with the default qdiscs (mq + fq_codel), at line (gbit) rate, result in it locking up *for any other traffic, including ping* until the first netperf is more or less complete. I fear the underlying driver is frightfully overbuffered, or has another problem. http://snapon.cs.kau.se/~d/archer-c7/onenetperflockout.png (needs BQL, too) The still bad news: cake works in both directions for a while longer, then goes boom similarly. The somewhat good news: cake "shaped" to 900mbit on inbound and outbound to the router - does not lock up the router. It merely runs out of cpu, but still does manage quite respectable throughput in both directions while doing so. Note, I did not say "latency". http://snapon.cs.kau.se/~d/archer-c7/encouraged.png As usual there is some flent data in that dir if you want to draw your own plots. I was not in a position to actually test traffic through the router (because I had the archer setup to do that) I wouldn't draw any conclusions from this. Well, a safe conclusion, is: don't install this build.
