55 million items in your hash? One wonders where all this data is coming from. It will take quite a while just to read in that many items.

If you have to re-do the duplicate check a few times (say every-time new data is added to the set), perhaps now is the moment to store the data in a database and use the database-engine as your duplicate-detector.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
