I am trying to understand why the Flow Accumulation generation in SAGA is much slower than in WhiteboxGAT. In fact, I couldn't wait for SAGA to finish processing. In both tools I tried to follow more or less the same steps: 1) Fill Depressions (Wang & Liu) 2) Flow Accumulation Parallelizable (D8 Flow Accumulation, in WhiteboxGAT) The objective is not to make a comparison, but to understand why I am having such a difference in performance. Am I doing something wrong?
