These benchmarks are intended to compare the overhead of async-await vs. a naive promise implementation vs. the babel async-await transformation. The functions in the benchmark don't do any work themselves, so results should reflect only overhead of the chosen implementation. Current numbers on my local machine (higher is better): BaselineES2017-AsyncAwait(Score): 2006 BaselineNaivePromises-AsyncAwait(Score): 7470 Native-AsyncAwait(Score): 3640 BUG=v8:5639 Review-Url: https://codereview.chromium.org/2577393002 Cr-Commit-Position: refs/heads/master@{#41860}
