If you want to compare various stunnel versions, then use the same<br>
OpenSSL version. If you want to compare OpenSSL... then use the same<br>
stunnel version. The configuration you mentioned above doesn't make a<br>
lot of sense as it makes it hard to tell where the performance drop<br>
comes from. If you really must test such configuration, the best way<br>
would be to ensure the same TLS version (1.0, not 1.1 or 1.2, OpenSSL<br>
1.0.1 defaults to 1.2) and the same cipher.<br>
