A rough benchmark Quinn did comparing the HAM algorithm (I wrote it some years back) to the well known Spring algorithm.
Apparently on his test the Spring algorithm took 2s to complete and the HAM algorithm only 21ms, they are otherwise very similar algorithms in terms of their results. I've found these results are pretty typical of past benchmarks I've seen. QT: https://blob.cat/objects/72009077-4cef-4444-ad2f-f27a169acdee
