How to speed up the Rust compiler in July 2026
My last post on the Rust compiler’s performance was in December 2025. Let’s see what has happened since then.

I just rewatched season 1 of Andor for the fourth time. It's my favourite TV show. It's not just another Star Wars show. There are no Jedi, no Skywalkers, no lightsabers, and no Force. It's just rebels and Empire. Everything has depth and weight. Everything feels real.

How to speed up the Rust compiler in December 2025
It has been more than six months since my last post on the Rust compiler’s performance. In that time I lost one job and gained another. I have less time to work directly on the Rust compiler than I us...

Faster Rust builds on Mac
Did you know that macOS has a secret setting that can make Rust builds faster? It can also make Rust tests faster. It probably even has similar effects for other compiled languages such as C, C++, Go,...

Speed wins when fuzzing Rust code with #[derive(Arbitrary)]
If you are using #[derive(Arbitrary)] to fuzz your Rust code, update the Arbitrary crate to v1.4.2 to get some compile time reductions and possibly some fuzzing speed improvements.

How much code does that proc macro generate?
Rust’s proc macros are powerful but tricky, and have some compile-time costs. This post is about a new tool to help quantify and reduce some of those costs.

How to speed up the Rust compiler in March 2025
It has been just over a year since my last update on the Rust compiler’s performance. Let’s get into it. The information about metrics at the top of this post still applies.

Streamlined dataflow analysis code in rustc
Sometimes I pick a crate in the Rust compiler and read through its code to learn about it and find things that I can improve. Often the improvements are small, but sometimes they snowball.
