I am trying to reproduce this with veth to no avail.
I compiled a net-next kernel with Toke's configuration, and simplified
veth to only a client and a server.
The client upstreams to the server and has cake setup; testing with
tcp_4up on the client. The setup is attached, untar, run vsetup.sh
followed by mm2.sh.
cake with unlimited bandwidth, rtt 100ms:
tc qdisc add dev client.l root cake
avg median # data pts
Ping (ms) ICMP : 0.01 0.01 ms 343
TCP upload avg : 17594.81 17933.86 Mbits/s 301
TCP upload sum : 70379.25 71735.44 Mbits/s 301
TCP upload::1 : 16148.03 17884.60 Mbits/s 300
TCP upload::2 : 18783.95 20993.83 Mbits/s 300
TCP upload::3 : 17774.41 19560.33 Mbits/s 300
TCP upload::4 : 17672.86 21154.05 Mbits/s 300
cake with bandwidth at 60gbit, rtt 100ms:
tc qdisc add dev client.l root cake bandwidth 60gbit
avg median # data pts
Ping (ms) ICMP : 0.01 0.01 ms 343
TCP upload avg : 15971.90 15149.72 Mbits/s 301
TCP upload sum : 63887.59 60586.67 Mbits/s 301
TCP upload::1 : 16903.57 17989.00 Mbits/s 300
TCP upload::2 : 14248.18 11982.24 Mbits/s 300
