In concrete terms, here is the C code to compute the remainder of the division by some fixed divisor d : uint32_t d =. ; // your divisor > 0. The divisibility test is similar… uint64_t c = 1 + UINT64_C ( 0xffffffffffffffff ) / d ; // given precomputed c, checks whether n % d == 0. I make my benchmarking code available.

Why do we run Performance Tests on commits? It’s harder to reason about the performance profile of pre-production code since we can’t gather real-time metrics for code that hasn’t yet shipped. By running performance tests against every commit (pre- and post-merge), we can detect potentially regressive commits earlier.
