* Benchmark different versions of same or similar gems * Copy & Re-namespace any gem to benchmark side-by-side with `benchmarks-ips` * Enforce Gemfile version constraints * Regex search across all installed gem's source code to find issues quickly * Trim down app load times by keeping your worst players on the bench (useful for beating Heroku slug load time cutoff)
