If you want to compare various stunnel versions, then use the same OpenSSL version. If you want to compare OpenSSL... then use the same stunnel version. The configuration you mentioned above doesn't make a lot of sense as it makes it hard to tell where the performance drop comes from. If you really must test such configuration, the best way would be to ensure the same TLS version (1.0, not 1.1 or 1.2, OpenSSL 1.0.1 defaults to 1.2) and the same cipher.
Hi Janusz,
As per your suggestions and mea culpa in some stated results. Here is a hopefully complete/better matrix. Making sure that CPU is pegged at 100% and in stunnel.conf (sslVersion = TLSv1)
stunnel 4.29, OpenSSL 0.9.8o - ~300 requests per sec stunnel 4.29, OpenSSL 1.0.1e - ~360 requests per sec stunnel 4.56, OpenSSL 0.9.8o - ~100 requests per sec stunnel 4.56, OpenSSL 1.0.1e - ~120 requests per sec
Regards.
