I'm comparing the behaviour of two pieces of SFTP client software. They're doing the same SFTP download, but one is 15 times faster than the other. Some analysis has led me to believe that the problem may be related to PSH flags. Both are downloading data in chunks of 32,768 bytes. In both cases the data is transferred back from the server in packets of size 1,360 bytes. In one, every packet has the PSH flag set. In the other, only the final packet of a chunk has the PSH flag set.

My question is: what, on the client-side, is causing this difference in use of PSH flags?
