read in small chunks the operation can be very slow. The use of a read only

a buffering BIO to the chain will speed up the process.

This is the number of bytes that the client sends to the server, and then
the server sends back. Because this is all happening in one process,
the data is being encrypted, decrypted, encrypted and then decrypted again.
What does this all mean? Well for a server, with no session-id reuse, with
