in thread Reduce CPU utilization time in reading file using perl

Hi Laurent R
Thanks a lot for your clarification. My CPU is 4 core so it looks like only 1 core is used for this process and that is why it is showing around 23% out of total 100% capacity of the CPU. I need to read two large files and find the difference based on column and store the differnces in the third file. Can I use threads here to read this huge file and store it into a hash. Or is there there any other better way to handle this. Please suggest.
Thanks
madtoperl

[Corion]: Meh. I need to find myself a better "programming" feed than r/programming (which is just HackerNews reposts and advertisements, very little code). Maybe I should select a list of links that I liked on r/programming and then google for ...
[Corion]: ... an aggregator site that also listed (ideally) all of these links once. And maybe also have an exclude list to blacklist some of the most spammy links that the site may have never mentioned at all
[marto]: I gave up reading HN at all, and feel much better for it :P
[Corion]: Now, how to best automate that Google search ... :-)
[Corion]: marto: Yeah, I'm also short of not reading it at all. I already stopped reading it in the morning because it gave me a foul mood.
[Corion]: The good posts on HN are the non-computing posts. Most of the other stuff is maybe relevant to you if you are 20 and live in Silicon Valley...
[Corion]: Two attributes that don't describe me.
[Corion]: Maybe I should also write a curator for HN or simply not read it anymore, like you do.
