Good to know. I think indicates that sharing an SSL_CTX across multiple threads is not a source of contention, with any hot locks on the libctx and not the SSL_CTX side. This is good to know. |

There does not seem to be much of a difference between using a pool of lib_ctx with allocating ssl_ctx per thread, and having pre-allocated pool of lib_ctx alongside associated libctx.
