Measuring the overhead of WebAssembly using libsodium

Now that LLVM has native support for WebAssembly and that the WASI interface has been proposed by Mozilla (and immediately got a lot of traction), it’s time to add a new officially supported platform to libsodium: . In that context, the only difference between native builds and WebAssembly+WASI builds is the fact that in the latter, the code is compiled to WebAssembly before being eventually compiled to native code. Beyond the fact that runtimes still have room for more optimizations, these results also suggest that it may be worth writing optimized path-critical WebAssembly code manually, or using different tools than a non-specialized compilation toolchain.
