2. The average CPU-time it takes to perform a CREATE/CREATED

handshake.

This "depends" entirely on your CPU and which handshake is used, though I don't particularly consider TAP handshake performance relevant because it is slow and superseded by ntor.

`src/test/bench` will give concrete numbers (~140 usec on a modern Intel processor).

This is what I was looking for. Running the benchmark on two very different systems was revealing: on my Pentium G620 the ntor server-side time was ~300 uSec, an Allwinner A20 system completed the server-side code in ~10600 uSec.
