Rust Performance vs C Performance

Benchmarks and Reality

Rust matches C performance in release builds by compiling to optimized machine code with zero-cost safety abstractions.

Rust and C achieve comparable performance in release builds because both compile to optimized machine code, but Rust adds safety checks at compile time without runtime overhead. Use cargo build --release to generate optimized binaries that match C speeds.

cargo build --release

The compiler applies aggressive optimizations like inlining and loop unrolling, ensuring safe abstractions like iterators and ownership do not slow down execution.
