Performance of Rust Language [pdf]

Rust is a safe, low-level system programming language competing with C++. This article explores whether Rust's safety features compromise its performance and discusses best practices for optimization.

Rust is defined as a safe, low-level, system programming language directly competing with C++.

How much does it pay for safety in terms of performance ? Can we expect similar performance on idiomatic code ?

In this talk we

identify performance weak spots (and strong points) of Rust
check how bad (or good) they are in practice
propose countermeasures / performance best practices
Slides: English and Russian
Reading materials
Various posts and papers which served as base for slides
Rust performance features
Pros and cons of language from performance standpoint
Benchmarks
Projects used for Rust benchmarking
Script of the planned talk (outdated)

The talk was delivered at C++Russia 2026 and also published on
