Hi Marcel, Funny coïncidence ;)
I ran also some load tests lately, I haven't seen this behaviour using the same 3 fully connected nodes topology. I was using qpid-dispatch@1.0.1 and qpid-proton@0.21 My workload consisted in sending RPCs[1] through the mesh. - 10K clients / 20 servers - clients send at 1msg/s that leads to 10K msg/s on the bus for "fire-and-forget" RPCs and thus 20K msg/s for "request/reply" style RPCs. Note that the above - uses small message size (approx 1KB) - the load lasted only 5 min but was repeated with different number of clients. Thus routers were up for 3 hours. - clients connections were balanced on the 3 routers. I'm afraid I can't help further but I'll be although interested in the discussion.
