Ruby is a garbage collected language. It automatically allocates memory when objects are created and releases the memory when it detects that an object is no longer used. This means that the garbage collector is involved in the whole lifecycle of objects, so optimizing the memory layout of the garbage collector has the potential to improve the overall performance of the Ruby interpreter.If you’re interested in how the garbage collector works for Ruby 3.0 (which is still largely applicable today), check out my earlier article.
