Description

A dataset of 300 records in a table using ui-sortable has a 3-4 second delay after the item being dragged is dropped that appears to be related to sorting the newly ordered data that prevents any actions from occurring until complete, which includes any further dragging and even scrolling the page.

Contributor guide

Research direction
Investigate the sorting performance issue by profiling the AngularJS digest cycle after drop. Consider debouncing the sort update or using requestAnimationFrame to defer DOM changes. Alternatively, explore virtual scrolling or reducing DOM elements in the visible viewport.
