Viiite brings tools to benchmark and analyze the complexity of your algorithms. It has been designed as an alternative to Benchmark that let your benchmarks evolve smoothly from simple measures to more complex infrastructures.
[sudo] gem install viiite
Viiite uses semantic versionning and has not yet reached the public API required for 1.0.0. The safe way to require viiite for now is as follows:
gem "viiite", "~> 0.2.0"
