Hello, Monks:

I have a file, like this:

AAAAAAAAAA1111BBBBBB222222
BBBBBBBBBB2222CCCCCC333333
CCCCCCCCCC3333DDDDDD444444

[download]

and I need to make it look like this (same records):

BBBBBB1111222222AAAAAAAAAA
CCCCCC2222333333BBBBBBBBBB
DDDDDD3333444444CCCCCCCCCC

[download]

This is not for a school assignment, it's seriously one of the business requirements (don't get me started).

I am mostly curious what the best way to perform something like this would be, and what would offer the best performance. I will likely have to do this for about 10 million records per day, and I would like to have it done in under half an hour per day.
