WebAssembly Performance Benchmarking: criterion.rs, Native Comparison, and Memory Profiling

WebAssembly is fast — often within 10–20% of native performance — but "fast" is relative. Whether your Wasm module is fast enough depends on the baseline, the workload, and the runtime. Benchmarking Wasm requires measuring both the Wasm execution and comparing it against native, and tracking performance over time
