@loke Try running it with -Xint which disables the JIT compiler and check if you get consistent results. If both functions then take equally long, the JIT is confirmed as the cause.

@loke You can also look for "made not entrant" in the JIT log. It means a compiled version was invalidated and the hot method falls back to the interpreter.

@jbarop I can confirm that with the compiler turned off, the numbers are very consistent. Much slower for sure (about 150 times slower), but just as consistent as they are when using the JS and native backends.
