My last post on the Rust compiler’s performance was two months ago and a lot has happened since then.

My last post on the Rust compiler’s performance was in December 2025. Let’s see what has happened since then.

Summary: An AI agent of unknown ownership autonomously wrote and published a personalized hit piece about me after I rejected its code, attempting to damage my reputation and shame me into acceptin…

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...

I am happy to announce that I have joined a new startup called VectorWare. The linked website is currently very bare-boned, but the company aims to use Rust to improve the state of GPU programming.

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,...

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.

For the past 3.75 years I have been fortunate to work on Futurewei’s Rust team, where I had enormous freedom to “make Rust better” however I see fit. It has been the highlight of my career and I am gr...

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.

My house is now free from the direct burning of fossil fuels. Here’s how I did it.

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.

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.
