Rust developers often complain about long compilation times which affect productivity, but the Rust Project is actively working on improving compiler performance.
Significant improvements have already been made in build performance over recent years, though it is still a concern for many users due to complex features in Rust.
Achieving fast compilation times is challenging due to Rust's complex type system, borrow checking, and other technical factors, as well as trade-offs between performance and other priorities.
Contributors face technical challenges in improving compiler speed, like understanding the large codebase and balancing trade-offs with existing optimizations.
Improvements are ongoing, utilizing approaches like parallel processing, caching, and source-level optimizations, but wider implementation is currently limited.
The Rust Project relies on volunteers who contribute based on personal interest, which can affect the rate of progress in performance enhancements.
Funding and supporting long-term development are critical to maintaining and enhancing Rust compiler performance.
