I suggest you re-read https://en.wikipedia.org/wiki/Nagle's_algorithm
Nagle only kicks in when there are un-acknowledged packets.  So on the
first packet, there is no delay.  There will be a delay on the *second*
packet if it's small and we haven't yet received confirmation that the
first packet was received.
