Maybe...in fact now I'm specifically wondering if it may have a bit to do with graphics hardware--my example machine has a Via Chrome 9 (integrated graphics). Hmmm... > FF2 is a bit slower than IE 7 when it comes to math which might > explain that a little > http://www.codinghorror.com/blog/archives/001023.html Most interesting! I had known IE was slower in general, which was why I was surprised that it was faster in this case--but that benchmark graph is worth a thousand words, showing that most of its poor performance is string operation related. Who knew? But what still puzzles me is why FF on *Windows*, specifically, is slower! It's the same JS engine, right? Yet it performs much better-- and on inferior hardware--under Linux than Windows, and also works fine on a comparable Mac. Weird! Maybe I'll run that benchmark against FF/Win and FF/Linux and see if anything jumps out at me. > have you tried stripping it your code back to see if a basic version > runs faster in FF ? That was what I had on the list to try next, but I didn't know where to start. I still can't figure why that would be significantly different than just turning all the layers (besides the base layer) off...I don't have any pan/drag/mousemove event handlers that run all the time...to my knowledge, anyway...
