Scroll lag + performance issues + alternative + general feedback

I've been having an issue with scroll lag while updating the table. The normal 'lag' for virtualization is reasonable (still disappointing) but things get worse when updating data that is being sent from the server (realtime application). Data is being pushed every 0.5s and that could be an add,update or delete. The data is also sorted so new items can jump in on various locations.

I find it hard to plunker this because it doesn't illustrate an real scanario, I did my best. Best is to close the script and hide the side panel to have the full width. Don't mind the initial load, it is generating data in javascript, takes some time. https://embed.plnkr.co/eef0CMMGo7Ih2U7pS5xW/

What I have noticed mostly is the angular timers being fired, for the digest cycle.
