Investigate the effect of Nagle's algorithm of the request performance

[mshustov]

Nagle's algorithm delays data before it is sent via the network. It attempts to optimize throughput at the expense of latency.

In any non-pipelined stop-and-wait request-response application protocol where request data can be larger than a packet, this can artificially impose a few hundred milliseconds latency between the requester and the responder.
