[tpm] Single thread Perl 5.8.8 vs. Multi-threaded Perl 5.10.1

Hi J. Bobby,
My company uses Perl scripts to upload ASCII text data files into Oracle. The uploads happen on a system that can handle up to 32 threads. So multi-threading is still of massive time benefit even though we had to have numerous threads to overcome the initial decrease in performance from single to multi-threaded Perl. The uploaders currently run with up to 12 threads as the benchmark study showed that more than that had very diminished returns for our system setup.

I can't think of many situations where multi-threaded perl would be beneficial. I can understand if you were trying to make a Perl/Tk application appear snappier, or have it do graphics (animation) and accept input simultaneously.. but would there be other, more common situations where multi-threaded perl would be considered?

People will keep trying to get the application level to do the OS's jobs.
Unfortunately, threading seems to be a problem even the OS people haven't
