Poisson Benchmark
Numpy vs Rust vs Python using Py03 bindings
bench_poisson.py(Python, numpy) (single threaded)bench_poisson_rust.py(Python calling Rust using Py03) (Multithreaded)fish-rs/target/release/fish-rs(Rust) (Multithreaded)
Quickstart
Create a new virtualenv, install numpy (required by bench_poisson.py), install maturin (required by bench_poisson_rust.py).
virtualenv .
pip install numpy maturin
source bin/activate
Build the Python lib using maturin (-r means build in release mode).
maturin develop -r
Build fish-rs binary for reference:
cd ./fish-rs
cargo build --release
Results
Time for generating 10_000_000 values with a Poisson distribution.
