Good Day BrowserUk,

Your 'C' example brought up a very good point, and one that I've been pulling my hair out ever since your response. I re-wrote the script to use 'fork' to see how multiple processes would run. To my amazement the higher the fork number the greater the throughput. Since the test machine has 6 core and with 6 forks, all cores are running at 100%, adding more processes should not improve the wps. But it did! I just got better and better throughput.

But, because I'm using a file, I could look at the contents and the more processes, the more corrupt the file became. A little while ago, I found my problem.

The 'flock' function wasn't working with the 'sys...' functions ( sysread, syswrite, etc ). I still want to check this out, but I wanted you to know that my new good numbers are way less than what I originally published.

Regards...Ed
