Jonathan Ellis resolved CASSANDRA-3254.
---------------------------------------

    Resolution: Won't Fix

Thanks a ton for exploring this. Sorry to be a hardass but it looks like the quick fix is only a win for some workloads, and the more complete one is more than I'm comfortable with for the stable release series (especially with 1.0 right around the corner if you need the optimization).

> MessagingService is calling DataOutputBuffer.getData() instead of .asByteArray() in two places. This results in always sending the full buffer size of at least 128 bytes even if the message is smaller. For messages like gossip and single col mutations its around 40 to 80 bytes wasted per message.
