Since recently the Wasm interpreter is running faster via Wasmtime than native for some test cases which is very weird since usually the overhead is between 50-100% of native. Note that on other machines native performance is far superior. So this mostly affects our benchmark infra and also my MBP M2 machine. After lots of thinking and experimenting I am kinda out of ideas for what could cause this and would really love if someone is willing to throw in a hint, a wild guess or their thoughts. Thanks. :)
