| Script used: | |
| https://github.com/kyrylkov/promise-async-performance | |
| Platform info: | |
| Darwin 19.0.0 x64 | |
| Node.JS 10.15.3 | |
| V8 6.8.275.32-node.51 | |
| Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz × 8 | |
| Conclusion: | |
| The performance gap is closing between callbacks and native async. | |
| - 2018 - Node 8, callbacks are 300% faster ([source](https://gist.github.com/ColonelBundy/d57fb9cd16eb87b2d4d932acc1055b30)) | |
| - 2019 - Node 10, callbacks are 110% faster | |
| - 2019 - Node 12, callbacks are 75% faster | |
| This was an updated follow up on the performance benchmark from [kyrylkov](https://github.com/kyrylkov/promise-async-performance) and modeled after the Gist from [ColonelBundy](https://gist.github.com/ColonelBundy/d57fb9cd16eb87b2d4d932acc1055b30). |
