compile time
lcnr opened this issue · comments
While incremental builds are fairly fast, a fresh cargo build requires 2m51 on my setup.
cargo build --release takes 7m44
It should be possible to reduce this by cleaning up the used dependencies
How long does it take with:
[profile.dev]
opt-level = 2
cargo clean; time cargo build
Haven't tried it myself yet
Seems its not faster (I had read about it on https://github.com/hecrj/coffee) it might be a crate size thing?
[cargo clean; time cargo build]

[cargo clean; time cargo build] #opt-level=2

its actually slower 😱 That's interesting 🤔
It might be a one of thing, but 12 whole seconds tells me its either equally as fast or slower
