In order to demonstrate advantages of U++, we have reimplemented some examples of other libraries.
Comparison vs Qt
Comparison vs Java/Swing
Comparison vs wxWidgets
To demonstrate how not using standard C++ library affects application performance, we have provided following comparison:
U++ Core vs C++ standard library benchmarks
U++ Core vs D programming language
Before following those links, please keep in mind that similar comparisons are always a little bit tricky. While we have tried to be as fair as possible, we were reimplementing tutorial examples which are quite specific stuff. Anyway, if you feel like we have harmed you favorite platform, nothing prevents you to implement those applications in more optimal way or suggest improvements - we will be glad to use your version here.
