Reduce builder size of jobs that take less than an hour
The current longest build time is ~2hr for the `dist-x86_64-linux-alt` build. This is already on a 16-core builder, so we can't make it any faster (by throwing more hardware at it).
Given that overall build times will be at least 2hrs, we can reduce build costs by reducing the builder size for any job that takes less than 1hr since it will still complete before `dist-x86_64-linux-alt` does.
Note that scaling isn't linear, halving the core count increases end-to-end build times by about 25-50%. In [this sample build](

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
