I am confused for the same reason you are. Isn't the rust code just "pre-jitted" code essentially? i.e. hand optimized. You are going to want to hand-optimize some functions in cases where the jit cannot do a good job in its current form. You probably also want a benchmarking system where you compare the jitted code to the hand optimized code, to prove to yourself that the hand optimized code is still worth keeping, after any automatic jit improvements you make. And if you don't want the runtime overhead of the jit then you can pre-jit certain functions and distribute them as part of the binary's executable code
