What are you disagreeing with? There's some baseline amount of I/O that the kernel does for you, that's what I'm assuming is 50ms, and everything else like runtime degrading is overhead due to the language/platform choice. I'm saying Rust is upwards of 100x faster in that regard thanks to its zero cost abstraction philosophy. You can't just include the I/O baseline in a claim about Rust's performance advantage. You'll be really disappointed when Rust doesn't download your files 100x as fast as the Python file downloader.
Anyway, I'm sorry I provoked your antagonism with my terse messages, I wasn't trying to be blase. I believe uv is the sort of tool that wouldn't suffer much from the downsides of Python and that in most situations the reduced runtime overhead of Rust would have a negligible impact on the user experience. I'm not arguing that they shouldn't build uv in Rust. Most situations is not all situations, and when a tool is used so widely you'll hit all edge cases, from the point where the 10s of milliseconds of startup time matters to the point where Pythons I/O overhead matters at scale.
