I did similar Rust/Python record generation experiments, and I can relate to these numbers. However, I think your Rust threaded trial might be a little bit off in subtle ways. I would truly expect it to perform about several times better than single threaded Rust and async Rust (async is generally slower on these workloads, but still faster than Python) Edit : After reading your rust code, you might have room for some improvements : - don’t rely on random, simply cycle through your values - pre-allocate your vecs with ˋwith_capacityˋ - dont use channels, prefer deques.. - ..or even better, don’t use synchronization primitives and open one connection per thread (not sure if it will work with sqlite?)
