 benchmark-memory is a tool that helps you to benchmark the memory usage of different pieces of code. It leverages the power of [memory_profiler] to give you a metric of the total amount of memory allocated and retained by a block, as well as the number of objects and strings allocated and retained.

-* Ruby 2.6
-* Ruby 2.7
-* Ruby 3.0
-* Ruby 3.1
