Results

A ratio greater than 1.0 denotes a possible regression (marked with :x:), while a ratio less than 1.0 denotes a possible improvement (marked with :white_check_mark:). Only significant results - results that indicate possible regressions or improvements - are shown below (thus, an empty table means that all benchmark results remained invariant between builds).
