To elaborate on GrandFather's comment:

4.5GB is a huge amount of data (the CPU appears to be processing a huge amount of data).

Whether or not you take GrandFather's suggestion to use HTML::Parser, you definitely want to take his suggestion of replacing the slurp with a record-at-a-time read.

A while loop reading a record at a time will allow for useful print statements for debugging or progress reporting.
