Benchmarking breakdown

Parsimmon is pretty fast, but we’re not sure which parts are fast and which parts are slow!

Add a benchmark folder with examples we can run and some kind of analysis (flame chart?) of where Parsimmon is slow.

We could use these results to make performance improvements to Parsimmon.

I guess we could check performance of the current version against the previous version? Do you think that seems reasonable?

Points of interest:

• Running the benchmark the browser is better as:

  • Can easily check on different runtimes.
  • Can easily use profiling tools in the browsers.
    • I know its possible from node.js too, but did not work as well for me.

• I normally use the benchmarks after each new feature has been implemented By comparing Dev version performance to the previous version performance regressions can be avoided…

• This benchmark uses both iframes and webworkers in an attempt to isolate the bench cases.

  • Not sure if profiling works with webworkers… (it works)
