Didn't noticed such slow perf at the time coding this example. What Java Version do you use?

[heyao]

1.8.0_40-b25

[winterbe]

Perf bug mentioned by @sdeleuze is fixed for 8u66. You could test with an older Java version like 8u31.

I was interested to see what the performance was like. I also wanted to try out the CompiledScript. Here is a commit that tries a hundred runs as-is then a hundred runs as CompiledScript. Plotting output out of mvn test shows on my macbook pro an average runtime of 12.3ms for the original approach and 10.7 for the CompiledScript approach.
