It can be but it never is.

  Especially after PGO (profiling guided optimization) gets most of the way there

  To re-optimize compiled code blocks isn't without effort. Google has publicly spoken about AutoFDO and Propeller [0], after Meta had open sourced BOLT [1] in 2021. AutoFDO has since been ported to Android and adopted by Yandex [3].

  But is that because of JIT compilation or other decisions for how the language should work (dynamic typing, GC, etc.)?

  Hard disagree. Many newer game system emulators (32-bit and up) rely on JIT or "dynarecs" to get playable speeds, and they pretty much all use high performance compiled languages already. They often double the performance over their interpreter or more.
