I would expect bsearch() to have similar performance to an RPG %LOOKUP using a binary search.

One factor that might cause %LOOKUP to be slower could be optimization, since the bsearch() function itself is presumably optimized. Another related factor could be the number of callbacks made to the comparison function.
