I do not believe that forking is going to improve the performance of this script as it appears to be very much I/O bound. Each child that is forked is reading the same file from the beginning to the end, correct? What you need instead is to be able to split the file up into chunks and have each process work on unique chunks and return the time deltas. Do you really want to complicate the process just to save a potentially small amount of time?

Oh i see now ... why don't you just output the work to STDOUT and use another script to collect the results? Seems much easier than trying to share data.
