Rust compiler performance survey 2025 results

[NewsBot]

A new Rust blog post/announcement has been posted!

Two months ago, we launched the first Rust Compiler Performance Survey, with the goal of helping us understand the biggest pain points of Rust developers related to build performance. It is clear that this topic is very important for the Rust community, as the survey received over 3 700 responses! We would like to thank everyone who participated in the survey, and especially those who described their workflows and challenges with an open answer. We plan to run this survey annually, so that we can observe long-term trends in Rust build performance and its perception.

In this post, we'll show some interesting results and insights that we got from the survey and promote work that we have already done recently or that we plan to do to improve the build performance of Rust code. If you would like to examine the complete results of the survey, you can find them here.

And now strap in, as there is a lot of data to explore! As this post is relatively long, here is an index of topics that it covers:

• Overall satisfaction
• Important workflows
• Incremental rebuilds
• Type checking and IDE performance
