xiaodai··on Do low-level optimizations matter? Faster quicksort with cmov (2020)

xiaodai··on Do low-level optimizations matter? Faster quicksort with cmov (2020)

The radix sort implementation is not optimal. Instead of sorting 1 digit at a time, it should be sorting 11 digits at a time to saturate the cache lines.

So the baseline radix sort can be even faster.
