Linux SCTP: what kind of performance should I expect from netperf?

[Dave Taht]

I was curious about sctp's performance characteristics on
AQM'd systems... so
I built netperf with sctp support, and ran a couple tests on
kernel 3.11...

+1: SCTP appears to work over IPv6
-1: Throughput is terrible


d at nuc:~/git/netperf$ netperf -6 -H snapon.lab.bufferbloat.net -t
SCTP_STREAM_MANY
SCTP 1-TO-MANY STREAM TEST from ::0 (::) port 0 AF_INET6 to
snapon.lab.bufferbloat.net () port 0 AF_INET6 : demo
