Subject: Re: Piggyback the final ACK of the three way TCP connection establishment with the data
Date: Thu, 22 Mar 2012 16:44:31 -0700	[thread overview]

I like piggybacking as much as the next guy, and pushed for a bunch of 
it in the past, but are the files being transferred really that small 
relative to the RTT that the savings of the standalone ACK of the 
SYN|ACK really buys that much?

I'm sure it does nice things for a default netperf TCP_CRR test, shaving 
one segment out of 8 or so, and maybe even more on a TCP_CC test, but 
how many sub-MSS files are transferred these days?
