These are just linear gradients with reflection (ie stripes) and solid fills. There are about 35 rooms on this map. Before I increased the MIN_REPAINT_TIME it would fill the rooms in 6 or 8 rendering updates, each updating a few rooms at a time. Increasing MIN_REPAINT_TIME lets it draw them all at once, and the total time to draw them is much less. It's as if there were some extra overhead associated with the rendering cycles themselves. The underlying map is derived from a AutoCad file and has lots of detail, so I don't know if that plays a part or not. It is a lot of SVG elements but they remain unchanged while the application runs. > > One thing that's interesting is that it seems that adding/modifying > > the "fill" attribute of a <polygon> directly updates slightly faster > > than adding a new <use> element which references the <polygon> with > > a different "fill".

Hadn't thought of that idea-- it definitely sounds like a good one.
