Bear in mind that I didn't do enough analysis to explain why the .offsetHeight code was so costly. It may be possible to tune this code and keep it in the browser. For example, you could maintain a separate document for measuring items, so you could measure without reflowing the main document. >> (2) 50% of time spent painting images...
