it's rediculous how much faster rust is with release flags
the only two times i've gone "wow this is slow" in rust, running it with --release made me stop saying that
@CobaltVelvet @catoutofbed how much of the debug information is retained in --release?
or is rust another one of those programming environments that doesn't need debugging in production?
@hirojin @CobaltVelvet @catoutofbed the release profile doesn’t disable debugging, it just cranks up optimizations (which are slow to compile and may make debugging more difficult)
@catoutofbed I once spent more than an hour debugging why a Rust program I wrote managed to be slower than its Ruby equivalent until I noticed I forgot to switch the paths in the benchmark to the release version
@catoutofbed quite a few times i thought i was making clever optimizations but running it with --release shown it wasn't that clever but the compiler is
