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 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• Script of the planned talk (outdated)
