|High overhead of C++ Array builtins in CoffeeScript|
|Project Member Reported by bmeu...@chromium.org, Oct 23||Back to list|
The coffeescript test in the web-tooling-benchmark shows a high percentage of time spent in C++ Array code, specifically Array#slice and Array#concat. There are probably a couple of low hanging fruits to pick here.
The CL https://chromium-review.googlesource.com/574710 by danno@ improves the coffeescript test by around 4%, so roughly half the overhead of Array#slice is gone. Now Array#concat and Array#push are dominating wrt. Array builtins.
