Which is probably one of the reasons why Julia takes ages to do a simple plot.

No, that's not why. You think there's considerable time spent in parsing? It's all code generation that takes time, which is the same thing that makes Julia powerful.

That’s LLVM as a JIT compiler. In pure byte-code interpreter mode, Julia is quite more responsive.

There's also compilation that happens in Julia. Like the type inference. Which is to say, the time isn't just spent in LLVM.
