Jonathan Ellis commented on CASSANDRA-3254:
-------------------------------------------

(Especially since for larger mutations the space saved is not as significant but you are stuck
with the extra copies.)

> 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.
