builds for my 10kLOC project, which is a workspace. These are the commands run from the root of the workspace. We could clean up some deps, we use quite a few crates, and we use a number of proc macros as well. In general I'd say we're fairly "worst case" for compile time.

cargo clean; cargo build; 4m20

Commenting out two lines of code in one of the services + cargo build; 0m14s

cargo clean; cargo build --release 11m43s

change 2 lines, cargo build --release 0m31s

I don't find this egregious.
