You talk about loading the whole file into an array even though you process it line by line. This is obviously a waste of memory. Read the file a line at a time.

So that leaves the size of the hash. You could start by using a more efficient data structure, such as Judy::HS. If that isn't enough, you could use a disk-based solution such as DB_File.
