Hi, Recently I ran a benchmark test 'Timing[50001!;]' on my linux box and the result was surprisingly poor. It took almost 212 seconds to complete the task. I tried to recompile my kernel, re-install the Mathematica3.0, but nothing can help it. Accidentally, I was playing around with my mouse during executing the above line. The result was improved. So I made another try. By pressing the Shift key which has no effect while the 'Timing[50001!;] was running, and the outcome was 59 sec! Very Strange. I turned off any power saving feature of my laptop and those of linux itself. Still I get two different running time. I also tried another benchmark notebook (I forget the homepage, but with the index about 4.9 for the PII 450 system) , and had the similar result: Without pressing key while running: it took about 516 sec(index 0.19) with a key pressing while running: it only took 176.2 sec(index 0.57) Why the Mathematica3.0 on my linux box was slowed down? Any help will be appreciated. System Info: linux 2.0.34, P100 Laptop with 32M RAM. Thanks for help!! -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
