Runs benchmarks against a range of Clojurescript versions and reports the results

branch: master
README.md

cljs-bench

Track how the performance of Clojurescript changes with each commit to the repository.

See the plots

Usage

Make sure you have at least one of these environment variables defined:

  • V8_HOME (location of the d8 binary)
  • SPIDERMONKEY_HOME (location of the js binary)
  • JSC_HOME (location of the jsc binary)

Also, make sure you have a recent version of Gnuplot on your PATH.

This assumes you already have a working Clojurescript that was cloned from git. Make sure you've run the clojurescript bootstrap script (script/bootstrap) to download Clojure and the Closure compiler. Create a file named last-head inside your copy of cljs-bench and put the SHA1 of the earliest version you care about in this file.

Then, if using leiningen:

lein run ~/src/clojurescript/ report

This will check out and run the benchmarks in every version of clojurescript between the version you mentioned and origin/master of the local clojurescript repository you pointed cljs-bench at. When its done it will update the last-head file to point at the current location of origin/master. To perform incremental updates, just fetch into your local clojurescript repo and run the above command again.
