Benchmark: Async vs Neo-Async

How to check

$ git clone git@github.com:suguru03/async-benchmark.git
$ cd async-benchmark
$ npm install
$ node . // It might take more than one hour...

Environment

  • Ubuntu v12.04
  • Node.js v6.2.1
  • async v2.0.0-rc.6
  • neo-async v2.0.0-rc.1
  • benchmark v2.1.0
  • func-comparator v0.7.1

Result

Neo-Async is 1.27 ~ 10.7 times faster than Async.

The value is the ratio (Neo-Async/Async) of the average speed.
