Did you actually benchmark this or do you just think this is the case? Consider that SSL_write/read will normally do something like AES or Chapoly on your CPU at a throughput of 2-4 GB/s, which is about an order of magnitude slower than streaming memory throughput. -Marian Am 02.02.20 um 15:27 schrieb Eran Borovik: > Hi all, > I am in the process of integrating OpenSSL with my application.
