Combining AngularJS with a Single Core CPU can result in nearly maxing out the CPU usage

I developed a robust AngularJS application that had been functioning well up until this point.
My issue arose when some users (using ancient computers with single CPUs) began reporting that the application was running unbearably slow.

Upon checking the task manager, I noticed that the CPU usage for the tab constantly ranged from 70% - 100%, especially on machines with just one core.

Given that the application runs smoothly on more powerful computers, I am uncertain if this is truly a performance problem. And even if it is, I'm unsure how to diagnose it since I can't rely on Chrome's performance tools.

Is there any way to address this concern? Can I instruct Angular to execute its digest cycles less frequently?
Has anyone else faced a similar challenge? Any advice would be greatly appreciated.

Answer №1

Discovering ways to minimize the frequency of cycle calls is a task I have yet to encounter.

Nevertheless, there exist numerous methods to enhance your application's performance.

To gauge your computer's performance, consider installing Batarang, which offers a performance analysis tab.

Once you have this tool at your disposal, you can concentrate on the following strategies:

  1. Turn off unnecessary watchers
  2. Avoid using ng-repeat whenever possible and opt for the bindonce directive instead
  3. Implement pagination to work with smaller data sets
