Well, just looked at this and a couple of reasons, one  being that I don't seem to have that rename program :)  The other is that with this option I'd have to run find twice (for the two different patterns) and running find seems to be what takes time.

If I run my dedicated Perl script it only needs to run find once which takes less than 2 minutes.

I counted the directories btw and out of 3300 directories it will typically change about 60 of them.
