 The lift-off mode compiles the wasm binary multiple times, progressively generating a more optimised executable with each iteration. Right now there will only be two iterations. Lift-off mode requires a hand-off process that can be a bit costly. This mode is useful for JIT scenarios where you need the module to start as fast as possible with deferred optimization.
 
-We are using OrcV2 because it promises concurrent compilation and makes JITing a lot easier with support for loading and dumping object code. It also opens the possibility of profile-guided optimization in the future.
