Well, it depends. Are you sure it's the Perl program that is the bottleneck? If the files are large, it may well be that the disk I/O or the terminal I/O is the bottleneck.

But if you want people to look at your code, you have to post it. But mind! If you cut-and-post hundreds of lines of code without much explaination, you are far less likely to get a useful response as when you post the relevant lines of the program, among with commentary.
