Computed.sort 10 times slower than sortBy

Hello

In my project I have an array with a few thousands elements which needs to be sorted. My first attempt was to use

dataSorting: ['property'],
dataSorted: Ember.computed.sort('data', 'dataSorting')

but I was disappointed with the performance. It took around 30 seconds to sort and display the array. My next attempt was to use

dataSorted: Ember.computed('data', function() {
  return this.get('data').sortBy('property');
})

and this solution takes only around 500 milliseconds to sort and display.

I was unsure if something else in my project is causing this behavior and I created a simple Ember Twiddle app to show the performance difference: https://ember-twiddle.com/5ed7c167f51d1532dcc08ddf0b271771
Perhaps my performance measurement is not totally accurate but it shows a difference between the two sorting methods.

Do I use Ember.computed.sort incorrectly or is it meant only for small arrays?

Thanks
