Re: Reduce CPU utilization time in reading file using perlby BrowserUk (Pope)

Using Tie::File on such a huge file -- or any file over a few (single digit) megabytes is stupid. It will use huge amounts of cpu and be very slow.
You can build your hash much (much, much) more quickly this way:
Will use far less cpu & memory and complete in less than 1/2 the time.
However, it is really doubtful that you will be able to build a hash from that size of file without running out of memory unless:
