And are you sure that your Doit is actually JITed in Cog?
1) always take the overhead of the loop into acount. Especially if it is a
large percentage, it
can make you "slowdown" seem very small even though it is huge.
e.g. the overhead of the loop in your case should be *very* high. 90% of the
execution time?
2) always make sure that you actually JIT.
-> put it in a normal method in a class
-> execute it at least 2 times
