Performance problem

[GitHubish]

I have performance problems with dom_autoscroller. I use Angular and Ngx-dnd. No worries for several years with these technologies no matter how many items are displayed. Nevertheless we wanted to add the possibility of being able to scroll while dragging and dropping. The addition of dom_autoscroller has been a concern but problems of slowness are immediately felt. The slightest movement of an element is very slow.

Any ideas?
