> The default for TCP_NODELAY in the IOReactorConfig is currently false.  This may be fine
for GET requests where the entire request is sent as a single packet, but it KILLS performance
for even simple POST/PUT requests as it waits for the ack for the headers before sending any
of the body.   It's obviously easily worked around by setting it to true, but it likely should
be the default to make sure that "out of the box" performance is fairly reasonable.
