Regarding SCTP performance

[vansi wow]

Hi All,
          we have ported SCTP from FreeBSD 7.0 tree  , but we face the
issue that when we measure the throughput performance of the stack , we see
that  SCTP throughput is half that of the TCP throughput .

Is there some tuning which can be done or some tweaks which can help
improve the performance .



TCP :
=====
SO_SNDBUF = 32768
SO_RCVBUF = 32768
Throughput: 5653KB/s


SCTP:
======
SNDBUF = 838860
RCVBUF = 838860
Throughput = 2422 KB/s
