It was just a quick test using the JSON data from
http://de.wikipedia.org/wiki/JSON#Beispiel

The following scripts were called using Lua 5.1.4 and measured using the
GNU/Linux "time" command. I used "-e" to add the necessary require-calls
for each JSON-module.

Those benchmarks might not be the best, I do not how representable the
test data is. I just wanted to give a rough orientation. In my opinion
standard compliance is a lot more important than speed.

Oh, that reminds me, I still haven't documented and published the new
version of my library that has been sitting on my hard drive for a few
months now. Is anybody except me actually using my library? I guess JSON
looks easy enough to tempt a "make your own" anyway. I mainly published
my version because I didn't find a version at the time that was standard
compliant -- except maybe Lua-Yajl, which only had a minor problem when
decoding.
