I think it quite good figures for arrow function:
                                                      before_patch                 after_patch
   arrowfunction-call-in-class-constructor          300.1710+-13.5061    ^    191.4837+-4.5846        ^ definitely 1.5676x faster
   arrowfunction-call-in-class-method                91.2163+-7.7129     ^     29.3135+-10.2887       ^ definitely 3.1118x faster
   arrowfunction-call-in-function                    96.5411+-31.9533    ^     19.6813+-1.5141        ^ definitely 4.9052x faster
   arrowfunction-call                                33.9300+-3.3111     ^     27.0056+-0.9594        ^ definitely 1.2564x faster
