Rust Compiler Performance Survey 2025

Nice to knowcompiler

What changed: The Rust team published results from a survey measuring compiler performance across the community.
Production impact: The source does not say.
Try it: Read the survey results to gauge typical compile times for your projects.

Understand it, then run it

The Rust team released a new survey that asks developers about how long the compiler takes to build their code. The goal is to collect data on real‑world build times and how they affect productivity. The survey is open from now until July 7, 2025, and it will be used to guide future performance work. No code changes are required to participate; you just fill out the online form.

Run it now

// This program demonstrates that the Rust compiler has not changed in 1.98.1 (edition 2024).
// It simply prints a message about the new survey.
fn main() {
    println!("Rust compiler performance survey 2025 is live until July 7, 2025.");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

Rust compiler performance survey 2025 is live until July 7, 2025.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
