Async function about benchmark.js

[jdalton]

@Philmod The async option is for executing each test cycle (and sample) asynchronously to give the UI time to update. If you want to test a synchronous operation you should use the defer option. Checkout the doc example here: http://benchmarkjs.com/docs#Benchmark (~middle of the example)

I can't do a suite test with this deferoption?

With this option, I can't test my function in parallel? (cause it waits the function to end before calling the function again)

I'm not sure I understand. Here is an example of setTimeout using defer:

I want to call the function in parallel, and then catch when all the callbacks are finished :

var start_time = new Date()
  , j = 0;
for(var i = 0; i < nb; i++) {
   setTimeout(function(){
    if(++j == nb) { // if all the callbacks have been called, calculate the time spent and so the number of operations by sec
      var end_time = new Date();
      var res = (nb / ((end_time.getTime() - start_time.getTime()) / 1000)) + ' qps';
      console.log(res);
    }
   }, 10);
};

You can construct something similar to this in your test body and then call deferred.resolved.
