SoundSplayTreeSieve

The SoundSplayTreeSieve benchmark reports the runtime of the sieve9 Golem benchmark for a SplayTreeSet from dart:collection and a SoundSplayTreeSet that declares variance modifiers for its type parameters.

Running the benchmark

These are instructions for running the benchmark, assuming you are in the sdk directory.

These benchmarks print a result similar to this (with varying runtimes):

CollectionSieves-SplayTreeSet-removeLoop(RunTime): 4307.52688172043 us.
CollectionSieves-SoundSplayTreeSet-removeLoop(RunTime): 4344.902386117137 us.
