# optimiz-rs v2.0 benchmark
|
|||
|
|
|
|||
|
|
Best wall-clock over a few runs. Single-threaded. Workloads chosen to be intrinsically loopy / sequential -- the regime where the Rust core delivers a real speedup over a NumPy reference.
|
|||
|
|
|
|||
|
|
Workloads that are fully vectorisable in NumPy (e.g. drift updates for an N-particle SDE with no callback) are not included: a tight NumPy loop on contiguous arrays is hard to beat from Rust through a PyO3 callback boundary.
