Subject: SCTP performance?

I just added some support for SCTP to my traffic-generator tool.

I tried to send 1Gbps of traffic, bi-directional, across two
10G interfaces.  TCP does this without any trouble at all,
but SCTP was asymetric and never got above around 700Mbps,
and was usually stuck at < 500Mbps.

perf top didn't show any obvious CPU bottlenecks.

Has anyone done any recent performance testing with SCTP?

I'd be interested to know the results if so...

Thanks,
Ben
