Results
This graph shows
- "init": time for the first step
- "step": average time for next 100 steps (normalized per step)
- I had to put time for first step of PersistentSAPCollider to log scale.
- Machine: Intel i7 2.7GHz, DDR3 RAM
- SpatialQuickSortCollider scaled with N^2 and is (significantly) slower, especially for big packings; the initial step is not significantly longer that regular step.
- PersistentSAPCollider scales with something over N×log N. The first step is significantly slower than the next ones.
- InsertionSortCollider scales the same as PersistentSAPCollider, but in absolute numbers is about 50% faster in regular steps and over 10x (!!) faster on the initial step.
