Compare one n-element hash#merge! vs n assignments with []= #198

Closed ohaleck closed 1 year ago

ohaleck commented 2 years ago

The code/hash/merge-bang-vs-[]=.rb benchmark merges N 1-element hashes to compare it with N hash element assignments using []=. Obviously assignments are faster, but this is not a real-life scenario.

The more common case would be to perform one merge an N-element hash and it appears it is much faster to do it than to perform N assignments. This PR implements such a benchmark.
