Re^4: Reduce CPU utilization time in reading file using perlby madtoperl (Hermit) |

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
