It doesn't look insane and sctp_wait_for_sndbuf may actually
have
something to do with a larger sctp_chunk I suppose?
The same perf record doesn't capture any sample for the good commit,
which suggests the nerperf process doesn't sleep in sctp_wait_for_sndbuf.
Ahhh yes! It does, and then it would mean your txbuf is too small for
the chunk sizes you're using (sctp tests option -m).
What's your netperf cmdline again please?
