The paper evaluates the performance implications of exploiting undefined behavior (UB) in C/C++ programming. It concludes that while there may be some potential performance gains, these are generally minimal and come with risks. In some instances, performance can actually degrade, but these regressions can often be mitigated through adjustments in compiler settings or link-time optimizations. This emphasizes the importance of careful management of UB in code to maintain stable performance while leveraging compiler optimizations.
