dannoHighBuiltinscoffeescriptHigh overhead of C++ Array builtins in CoffeeScriptStartedcrbug.com/v8/6978The profile shows a lot of time in Array#slice, which seems unnecessary.

LowICs, TurboFanjshintInvestigate high LoadIC/StoreIC usageAvailableWe might be doing something wrong here, especially since RCS suggests that LoadNonExistent shows up rather high. Maybe TurboFan is missing an opportunity here.

marjaHighICslebab, espreeSeveral deopt loops in lebab and espree testsStartedcrbug.com/v8/6980Profile shows several spikes of unoptimized code. Seems to be related to instance migration / map deprecation.

We should include either the confidence interval or the margin of error for the overall geometric mean as well
