<div dir="ltr">Hello Robert,<div><br></div><div>Thanks for your email!

Second, a suggestion for your consideration (_NOT_ a vile "feature request"):<br>
<br>
Have you considered allowing send buffers to fill a bit before<br>
sending? Not sending ASAP, but often sending more than one char<br>
per packet? Of course this increases latency, but reduces packet<br>
count _tremendously_ and data usage likewise since the payload is<br>
tiny compared to overhead (incl ACK)..<br>
<br>
Not sure how this would interact with SSP, but I hacked ssh to do<br>
this 10+ years ago. To minimize the latency when it would most<br>
annoy, the buffer was released if a command was received or when<br>
typing stopped for 300-600ms. Commands were considered to be any<br>
control-char or any duplicated char (likely to be cursor movement).<br>
<br>
Of course, latency is sometimes noticeable but that is the price<br>
of reduced transmission data. Most of the time, I'm typing blind<br>
anyways -- I'm not going to focus on the screen unless needed.<br>
Sometimes the reductions were as large as 70%, more often 50%.<br>
