In order to print the number of lines in the file, Tie::File has to read the whole file. To do this, it has to page it through it's buffer, which by default is only 2MB. Hence, it does a lot of memory shuffling which causes the symptoms you are seeing.

Try increasing the buffer size using the memory option. See the docs for details.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
