Review Comment:
See https://en.wikipedia.org/wiki/Nagle%27s_algorithm
Nagle only really applies for when the packets are smaller than the MSS
which is usually 1280 bytes. AFAIK only the HELLO message in TLS HS is smaller
than this; all other messages SHOULD be aggregated together by the SSL layer.
There IS a _well known_ interaction with Nagle and Delayed Ack which can cause
Nagle to be worse than it would be by itself. What is the order of delays you
are seeing?
