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

@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

igor, the blessed algorithm @hirojin

@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)
