If your statement that most of the time is in step 3 is true, I disagree with the other answers; you can expect to see a fair improvement renaming with perl unless Sun E-250 has lightening fast fork & exec.

Keep in mind that there's no reason not to mix bash and perl for different parts.

Might be helpful for you to show that part of your bash script.
