The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

Yet another wrinkle in the TLS library woes

I downloaded and compiled libretls, a libtls for OpenSSL. I also recompiled my Lua wrapper for libtls and reran the profiling tests from the other day.

I can now say for certain that there is no need to profile LibreSSL because the results speak for themselves—an accumulation of 24 CPU 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 systems, and there's probably little work to making it fast.

So now I have to rethink my using LIBRESSL_VERSION_NUMBER 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.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
