Given that we run PHP on the edge, what is the point of running the PHP interpreter on top of a WebAssembly interpreter (Wasmer) instead of just running the PHP interpreter directly?
The latter will always be faster.
The latter will always be faster.
The other caveats about "edge" throughout this discussion aside, if I needed to do this, I'd try to write something in Zig or (gag) JS or something else that compiles to WASM directly rather than writing a script for an interpreter that runs under WASM.
