Benchmarks hashing of the constant polygon. `pointInPolygon` hashes its constant polygon
|
|
argument once per block to look up the preprocessed polygon in the shared cache. A large
|
|
polygon combined with a small `max_block_size` makes that per-block hashing dominate the
|
|
run time, isolating the cost of the hash function from matching and preprocessing.
