The <> diamond operator, acting upon @ARGV is going to be tricky to get right, if you want to re-read the same file multiple times to benchmark. Better off using open to manually act upon the filenames passed into @ARGV. That way you can re-open for each run, or (probably faster), open once, tell, and seek to reset between iterations.

There are faster alternatives than <>, but if your drive is a mechanical drive, shifting over to SSD is the biggest win.
