I just ran the same TAK code and got an average CPU time of 1.06 seconds on a DN460 with 4 Mb, T 2.8, Aegis 8.0.1. I set (RECKLESSNESS) to 'HIGH, and the code used LABELS and fixnum arithmetic. If your times are way off from these, perhaps the discrepancy is in the measuring tool, not the code or the machine. What are you using to do the timing? -------
