In IE Edge, noticed this pen is very slow (but fine in ffox and chrome).  Figured out this performance hit disappears when removing the tweening of the opacity of the line elements.  To keep the effect of the animation fading in/out, I experimented and found I can instead tween the opacity on the parent element #map, and performance is great.  I suspect this is an IE Edge issue.  Maybe there is someone at Microsoft you can push?

 

I am posting here because it is very far and inbetween I encounter a performance snag when testing your library and was reminded of the old star-trek / star-wars hyperspace demo you used to have showing how great performance was with a jajillion elements moving at once.  I figured you would want to know when the experience was not stellar.

Unfortunately there are certain things that we simply have no control over, and browser rendering is one of those. As you suspected, it sounds to me like an issue with the browser itself not handling that particular scenario well (a performance bug). I'd be curious if it helps at all for you to merge the opacity tweening into the actual color tweening that you're doing. In other words, delete the "opacity" stuff altogether and just tween from stroke: "rgba(0,0,255, 0)" to stroke: "rgba(0,0,0,1)".
