You both get massively increased C call overhead and the worst case because you don’t get to hit a block until every 512/8 == 64 updates. Alas, openssl speed doesn’t distinguish between the same message sizes but in different chunk sizes, but you can at least clearly see the performance multiplier for larger messages. lvh _______________________________________________ Cryptography-dev mailing list Cryptography-dev@python.org https://mail.python.org/mailman/listinfo/cryptography-dev
