kids dont recall when chrome was cheating left and right to be faster than firefox (after they were honestly for a couple months).

you'd have to run benchmarks for all sort of little thibgs because no browser would leave things be. If they thought one popular benchmark was using string+string it was all or nothing to optimize that, harming everything else. next week if that benchmark changed to string[].join... you get the idea. your code was all over the place in performance. Flying today, molasses next week... sometimes chrome and ff would switch the optimizations, so you'd serve string+string to one and array.join to the other. sigh.
