> Thanks for the suggestion!  We are using rabbitmq-c.  I tried setting (TCP_NODELAY, 1) and the troughput increased from 20 msg/sec to 200 msg/sec.  As Tony pointed out in the previous email it was indeed caused by nagling.   it did not happen to tx_select but it happened to tx_commit.

Yeah, I suppose enabling tcp_nodelay would be more useful than
disabling it :)  Anyhow, glad to hear that it helped.
