improving profiles

[LuckyTurtleDev]

i have the issue with long rebuild times (not clean build). the most time is needed. the most time is needed by wasm-bindgen. so i tinker with the profile settingis a bit:

[profile] [profile.wasm-dev] inherits = "dev" opt-level = 1 #take above 12 s

[profile] # Enable a large amount of optimization in the dev profile for dependencies. [profile.dev.package."*"] opt-level = 3 [profile.wasm-dev] inherits = "dev" opt-level = 1 #take 8s

[profile] # Enable a large amount of optimization in the dev profile for dependencies. [profile.dev.package."*"] opt-level = 3 [profile.wasm-dev] inherits = "dev" opt-level = 1 #take 8s (most a little bit (0.2s) better than previous setting but in deviations)

[profile] # Enable a large amount of optimization in the dev profile for dependencies. [profile.dev.package."*"] opt-level = 3 [profile.wasm-dev] inherits = "dev" opt-level = 2 #take 8s. wider deviations. best case is faster and worst case is slower as settings before.

[profile] # Enable a large amount of optimization in the dev profile for dependencies. [profile.dev.package."*"] opt-level = 3 [profile.wasm-dev] inherits = "dev" opt-level = 2 #take 8s. slower as previous.

Conclusion:
I think the following setting are best i find. Activating max opt-level for all dependency speed up the rebuild process a lot. But it slows down the initial build massive. However since i need do to this only once i am fine with this trade.
However wasm-bindgen still take by far the most time. Did someone has ideas to speed up this even more?

[profile] # Enable a large amount of optimization in the dev profile for dependencies. [profile.dev.package."*"] opt-level = 3 [profile.wasm-dev] inherits = "dev" opt-level = 1

test setup
Nothing professional. i just take my current project and switch some enum values back and forward to trigger a rebuild at the cli.
I did this a view time and report the results.
A more professional testing would be better.
My project has currently some heavy dependency like Symphonia, but itself is still very small.
