WebbThe Rust compiler splits your crate into multiple codegen units to parallelize (and thus speed up) compilation. However, this might cause it to miss some potential optimizations. If you want to potentially improve runtime performance at the cost of larger compile time, you can set the number of units to one: [profile.release] codegen-units = 1.
