Rust developers acknowledge lengthy compiler times can be a significant issue that limits the productivity of developers working with this programming language. For helping in determining different combinations of issues around compiler performance, the Rust team has started a survey to collect more information on the issues.

Now through 7 July, the Rust team is carrying out a survey around the Rust compiler performance. Based upon the operating system, build system, and other factors they are hoping to collect more concrete information where developers are becoming challenged by slow build times. The survey includes looking at areas like CI/CD builds, Docker builds, optimized rebuilds, testing, unoptimized code generation, type checking, and other areas where the Rust developers hope to have a better understanding where developers are finding issue with the Rust performance.

In turn these survey results will hopefully allow Rust developers to better target areas of improving moving forward for the rustc compiler and related build infrastructure. Those wanting to participate in this Rust compiler performance survey can find out more details on it via the [1]Rust-Lang.org blog .
