Performance benchmarks of WebAssembly runtimes in 2026, highly novel and actionable for cloud and serverless architecture decisions.
Summary
WebAssembly runtimes WAVM, WasmEdge (with AOT), and WAMR (AOT) now run libsodium crypto benchmarks within ~2x of native x86-64, while wasm2c, Wasmer, and Wasmtime are close enough for CPU-bound workloads. The experimental `wide_arithmetic` instruction provides a significant boost for crypto code when runtimes support it. Node and Bun results were inconclusive due to insufficient JIT warm-up in short-loop benchmarks.
