Ruby micro benchmarks is a small suite to measure performance of simple Ruby methods and operators. Created in order to answer questions like what is faster array[0] or array.first, 'string' or "string", 'a: ' << a << 'b: ' << b or "a: #{a} b: #{b}". Results of these benchmarks are sometimes unexpected and interesting.
