The normal dragging is very slow and glitchy, but the only other effect I use so far is BlindDown and Up, which work ok. I went to the script.aculo.us SVN trunk and grabbed the draganddrop from the test directory (so it's beyond v. 1.5.1), so I could use the drag-scrolling effect. Lo and behold, when drag-scrolling is activated dragging is pure and smooth as silk (however turning it off results in the same slow, glitchy dragging as before). So clearly there is room for optimizations in these effects. From what I could tell the difference in the dragging function was that when doing drag-scrolling there is a setInterval call, so the processing seems to be more asynch. I'm sure that can be applied to the other effects as well. setTimeout and setInterval should be used wherever possible IMHO.

Create a todo list, then press 'open'. Add a few items (after about 8, is when it happens to me) then click close. THe animation is not very smooth for me, it only displays about 3 frames. This is not because it is pushing a lot of content down (look at the scriptalucous wiki effects treasure chest, that pushes a lot of content down with no slowdown. This issue has something to do with adding DOM nodes. The javascript that powers this is at http://rixth.org/lib/javascript.php (right at the bottom). Is this a known problem and does anyone else experience a slow down? My computer is reasonable, AMD XP 2800, 512mb RAM, it should be able to take simple web effects.
