I'm the author of Stitch. Rik is somewhat overpromising: Stitch is only faster than Wasm3 on Windows (by about 15%). On Mac and Linux, it is about as fast. It does get within 4x of Wasmtime (which is the JIT I've compared it against), but only on Mac. On Linux and Windows, it gets within 8x.

You should test it on a fast CPU tho on linux, its likely faster there. As you have said its likely an instruction cache issue.
