Benchmarks

Benchmarks are in the bench folder, and they can be run with the following commands, where {iters} is the number of iterations to run (defaults to 100). They use the luamark module

lx add lua-cjson dkjson lpeg luamark

# time benchmarks
lx lua bench/time.lua {iters}

# memory benchmarks
lx lua bench/mem.lua {iters}

Here is a comparison between cjson and dkjson (with the lpeg extension enabled):
