Profiling WebAssembly in Browser DevTools
The Performance panel's sampling profiler attributes time to individual Wasm functions, and with DWARF debug info plus the C/C++ debugging extension you get original source names, stepping, and memory inspection. Profile the optimized-tier steady state, and watch for time sunk in boundary glue rather than your kernels.
