the native executables native-image generates are usually a bit slower than hot-spot JIT'ed code (~10% on average according to one article).

they do need much less RAM and startup time is _a lot_ lower though.

here it is: "Right now peak performance is a bit worse than HotSpot, but we don’t want to advertise that (and we want to fix it of course)."
