I just discovered that changing DiffArray to a plain Array improves performance of my code by almost a factor of 10. Bitten by DiffArray yet again!
That's strange. Compiled without optimisations, using plain Array instead of DiffArray gives a speedup factor of about 38 here, with optimisations it's a factor of 100 (thus it's about on par with the list-only version of the same algorithm).
My mistake; I misread the time output. My results are the same as yours.
