Performance of Rust Language [pdf]

Source: Hacker News

Goal

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.

Contents

• Slides: English and Russian
• Reading materials – various posts and papers that served as the base for the slides
• Rust performance features – pros and cons of the language from a performance standpoint
• Benchmarks – projects used for Rust benchmarking
• Script of the planned talk (outdated)
