Thanks Vlad. I will try newer kernels and revert these changes
incrementally and see if there's improvement.

BTW: What tools are useful to monitor sctp behavior?
For this case I have been watching activity using
/proc/net/sctp/assocs, strace and tcpdump.

cheers,

PS: I currently have no choice on what kernels already deployed
that need the software feature but can make recommendations
for future upgrades. It would be good to narrow it down.
