Author here: we do have various numbers collected here, with varying levels of "I'm sure enough about these numbers to share them in a public blog post".

Compile time is on roughly the same order of magnitude as Ignition compilation (just AST to bytecode, so excluding parsing), and roughly two to three orders of magnitude faster that TurboFan. The relative performance to the interpreter, as the sibling comments point out, varies _wildly_ by workload, but around 4x is probably a decent approximation for something not entirely dominated by property loads.
