in thread Perl Program to efficiently process 500000 small files in a Directory (AIX)

Thumbs up, exactly the points I wanted to make.

Improvement is only possible after identifying the bottlenecks, and who knows how performant single file moves are on AIX ...

> 80,000 files per hour. 

Means about 4 per second that's hard to believe on modern hardware.

    80,000/hr /3600 = 22.222/s?

    Well I can assure you that you can believe it. Remember there are around 1million files dropped into this directory each day. Of these 1 million around half are the files I'm looking for to move into another directory. I commented out the "Move" out of the above script on this thread and it ran in 1 hour and 20 minutes
