I've timed Ack(3, 9) with an optimized Parrot build:

Python      13.7
Parrot -j   15.3
Parrot -C   13.8

Down now (r10445) at:

  parrot -C ack.pir             5.7s
  parrot -C binarytrees 16     1m14s

That is a little code cleanup was good for 100% speedup ;-)

This is a AMD X2 3800+ running at 2000 Mhz. It's BTW not easy to run benchmarks on that machine, the first few timings where 23-26 secs, obviously PowerNow had reduced cpu freq to ~50%.

Well powersave -f helps a lot,
