Profiling native code with optimizations on is very very tricky.
- JackYoustra 2y agoAgree, seems like a more likely culprit in this case.
- mwkaufma 2y agoWhat's the point of profiling for performance without optimizations if it leads you where the OP winds up hand rolling the same transformations?
