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):
