> 5. Unless there's something wrong with my benchmarks, encryption isn't quite as fast as I'd like on François's little low-power ARM box.
There was indeed something wrong with my benchmarks of ciphers and
hashes (but not digital signatures). Something so bone-headedly wrong
that I would prefer if you didn't look at this patch that fixes it:
Everything I wrote about digital signatures in the previous letter was
correct. As for ciphers, the performance is more than 1000 times
better than I thought.
On 64-bit servers, the it costs something around 10 *nanoseconds* per
byte, and on François's little low-power ARM box, it costs about 200
nanoseconds per byte.
