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 -- Ben Greear Candela Technologies Inc http://www.candelatech.com
