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.其他
