Nice! I've implemented that for Golang in the past and have ported it<br>
to C for you today.<br>
<br>
Although a single initial packet might seem more attractive in<br>
benchmarks, I found that sending two results in better catching parts<br>
of HEAD — which is what we want. Then you will notice some dancing<br>
around IW4, by which we've already sent about 5683 octets. Enough for<br>
me for a making a tradeoff here.<br>
<br>
16k as ssl->buffer_size results in partially filled packets. A better<br>
default value could minimize the overhead (<0.5%) for that trailing<br>
PDUs.<br>
<br>
SSL libraries really should provide a function for computing overhead.<br>
