True in general but some (especially libs aimed at larger datasets processed in batch) are taking advantage of benchmarks like this to do things like: Try the fast way, if it works great Try the slow way, if above fails This makes the slow path 2x slower at worst (and you can advise to always use the slow way with optional params) but the fast path can be 10x faster
