Personally, if I had a 22-core machine available to me, I'd be very dissatisfied with only being able to make use of 4% of the available power. I'd definitely look to multi-thread the processing so as to spread the cpu-intensive part(s) of the processing over more cores and reduce the overall time taken. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Yes, your script will be using 100% of one core, so if you have multiple cores, then the other cores won't be occupied. Your definition of a "problem" is still unclear - why shouldn't your script take 100% CPU? For a script that does a lot of CPU intensive stuff on a large input file that seems pretty normal to me.

Search the top documentation for "CPU" and try the "I" command to see the different ways CPU usage can be displayed.	[reply]
