.selectVS.eachVS.count

Benchmark to test the performance difference between Hash.select, Hash.values.count, and the old fashion .each iterator

Usage

• crystal selectvseachvscount.cr --release

Current Results:

Final Thoughts

• Looks like the old fashion .each iterator and .count are beasts! Assuming the benchmark is not skewed and correct (please submit a new PR to fix)
• Also seems like, sometimes developers can fall into the trap of using .select. However, if you just need to obtain the size of a hash / array, .count, and .each are much faster.

Contributing

• This is still a work in progress, if you can enhance this benchmark please submit a PR or issue, thanks!
• Thanks for stopping by!
