> 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.
