Info

ClojureScript PersistentHashMap performance test: assoc 4 elements onto a PHM vs. same for a defrecord with four fields vs. same for a defrecord with no fields. (NB. for the final case the extension map of the record will be a PHM.)

See CLJS-178.

For a readable version of the preparation code see https://github.com/michalmarczyk/cljs-persistent-hash-map-test.

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    m = null;
    k1 = phm.make_keyword("a");
    k2 = phm.make_keyword("s");
    k3 = phm.make_keyword("d");
    k4 = phm.make_keyword("f");
  };
</script>
