Some programmers are surprised by the performance of certain algorithms.
Is it only me..? Quicksort is supposed to be an algorithm that has O(n) to O(n²) performance and O(n log n) being only an average performance case.
Others are envious of those with low-level optimization skills.
I really envy programmers who are so skilled at this kind of low-level optimization. The same meaning, but different performance based on notation—it’s ultimately about entering LLVM’s optimization pass, which likely comes down to differences in the internal IR pattern.
Conclusion
Code speed is not always predictable. Even experienced programmers can be surprised by the performance of certain algorithms.
