Components Performance Concerns on Page Redraw.

[kaladay]

This doesn't haven't to be limited to just page redraw. The performance concerns are simply observed more easily on resizing the page or window.

Check to see if the problem is more so on TL-Components than Weaver-Components or not.

When moving the window or page size back in forth an aggressive amount of times in a short period of time, the system or browser can slow down noticable as the page attempts to redraw everything. In this particular case, it may be worth considering somehow forgetting redraws.
(Think of this as a Post-debouncer, that uses the values of the most recent browser state when redrawing and forgetting all of the other attempts to redraw up until that point, which is clearly not happening.) Currently, when aggressively resizing to a point that the browser slows down, you can see it going throw every resize attempt long after stopping.

This is also observable on DirectoryUI.
