Q++ Benchmarks

Cross-language benchmarks comparing Q++ against C, Rust, and Zig.

How to Run

From the project root:

.\benchmarks\run.ps1

With options:

.\benchmarks\run.ps1 -Runs 10 -Release

• -Runs N — Number of runs per benchmark (default: 5)
• -Release — Use release/optimized builds

Prerequisites

1. Q++: cargo build --release (compiler at target/release/qpp.exe)
2. C: gcc or MSVC (winget install mingw or Visual Studio Build Tools)
3. Rust: rustc (from rustup)
4. Zig: zig (from ziglang.org or winget install zig)

Benchmarks

Benchmark	Description
sum	Simple loop summing 1..100_000_000
fib	Iterative Fibonacci(40)
sieve	Sieve of Eratosthenes, primes up to 1,000,000
mandelbrot	Mandelbrot set 160x120 grid, 100 iterations max
nbody	5-body simulation, 50,000 steps

Results

(Run .\benchmarks\run.ps1 to populate)
