There is a performance manager in the administrative tools for most recent versions of Windows (not sure what Win 2003 is?)... that would probably be your simplest bet. You can view it on a per-process basis. I'm sure there's a perl module to access this data if you so choose.

However, I'm a little confused. You're slurping a file into a scalar and using a 500mb hash key? or the first line of that file takes 15 seconds to read? Also, does the read take 15 seconds and hash insert take 20 seconds (35 seconds total) or is the total 20 seconds?

One option would be to have a multi-threaded program where one thread reads the file and the other works on the hash.
