结论

Performance of Callbacks vs Promises vs Async Functions in Node.js v8  Node.js v8.4.0 (Carbon) / V8 6.0.286.52    Async Type  Time, ms    Memory, MB  Callbacks   376 73.55  Bluebird Promises   600 106.58  Async Functions + Bluebird promisify    636 114.67  Async Functions + util.promisify    1247    202.34  Native Promises + util.promisify    1274    195.23  Notes: both native Chrome V8 ES2015 promises and ES2017 async functions perform roughly 2 times slower than Bluebird promises using almost 2 times more memory.
