A recent talk at C++Russia 2026 examined Rust's performance characteristics against C++, addressing whether the language's safety guarantees come with significant speed penalties. The presentation analyzed real-world benchmarks to identify where Rust excels and where it struggles compared to traditional systems programming approaches.

The research focused on idiomatic Rust code performance, moving beyond synthetic benchmarks to evaluate practical applications. Presenters measured compilation times, runtime efficiency, and memory usage across multiple projects, providing concrete data on performance weak spots and strong points in the Rust language.

Slides from the talk are available in both English and Russian, accompanied by reading materials and benchmarking scripts. The findings suggest developers can achieve competitive performance with Rust, though certain patterns require careful consideration to match C++ efficiency levels.

The analysis concludes that Rust offers compelling safety benefits with manageable performance costs for most system programming tasks, making it a viable alternative to C++ in performance-critical applications.
