Arguably, the cost of 3 Rts is amortized over many many objects that gets transferred over the session. That said, I am trying to imagine how to do crypto on my Arduino :-).

So why are we okay with 10-20% more processing costs for everybody, but not

Personally, I thought that the first optimization was for latency,

How do you optimise latency by adding 3 RTs in a SSL setup?



with bandwidth as secondary and (obviously) consequential.  Trade-offs
may have to be made.
