Some heavily hit methods in the UIZE JavaScript Framework have been optimized to improve their performance.

Some profiling indicated that complex client applications using the UIZE JavaScript Framework tend to hit the Uize.clone static method quite heavily, so a little bit of code massaging was able to significantly improve the performance of that method by reducing the cost of recursion. The Uize.Population module - that gets used heavily for data driven population of UI widgets like droplists and scrolly based selectors - has been optimized to avoid using try and eval, resulting in a substantial performance improvement.
