I know you've already said you can't release the code of your actual project, but would it be possible for you to construct some test cases that demonstrate the speed penalty that you are suffering in 1.3 compared to 1.2? It would be interesting to see what circumstances are triggering this and whether or not 1.3 really is slower under some circumstances. I know the jQuery team prefer optimizing for the most common cases, it is possible that in doing so the library may become less optimized in terms of the less commonly used functionality.
