Hi Dave,
During a drag-n-drop reordering task, Gantt immediately changes task position and redraws all tasks. This is what causes low performance.
With 500-1000 tasks, reordering can work fine, with a larger number, it will take more time to redraw, and this is expected.
You can use marker mode to improve performance:

gantt.config.order_branch = "marker";

Here is an example in the snippet: https://snippet.dhtmlx.com/19f9uy7w.
