_runDelayedTriggers performance issue

[dpmragu]

I am facing performance issue when I load a large number of data set from my application. I used javascript profiler to identify the root cause. And found that one of the function _runDelayedTriggers() took long time in the backbone-nested.js(line number : 233) . Please refer the below screenshot that captured from Javascript profiler.

Can you please someone help to resolve this issue?

We've had the same issue and will supply a patch for this. The issue is that shift() is REALLY slow on a huge array. We've seen 15 secs just to shift() and array to nothing vs 3 ms to loop over it.
