                  Yet another wrinkle in the TLS library woes
                                        
I downloaded and compiled libretls [1], a libtls for OpenSSL (Secure Socket
Layer) [2]. I also recompiled my Lua wrapper for libtls [3] and reran the
profiling tests [4] from the other day.

I can now say for certain that there is no need to profile LibreSSL [5]
because the results speak for themselves—an accumulation of 24 CPU (Central
Processing Unit) seconds using OpenSSL vs. 1 minutes, 24 seconds using
LibreSSL. Looking at the results, it makes some sense. The LibreSSL library
I'm using the the “portable version” for non-OpenBSD (Berkeley Software
Division) systems, and there's probably little work to making it fast. 

So now I have to rethink my using LIBRESSL_VERSION_NUMBER [6] when compiling
the Lua module. I will no longer be using the LibreSSL version and I can't
exactly rely upon the TLS_API value either … sigh.
