perl

I know this is an absolute shot in the dark, but we're absolutely perplexed.

A perl (5.8.6) script run by Java (1.5) is taking more than an hour to complete. The same script, when run manually from the command line takes 12 minutes to complete. This is on a Linux host.

Logging is the same in both cases and the script is run with the same parameters in both cases.

The script does some complex stuff like Oracle DB access, some scp's, etc, but again, it does the exact same actions in both cases.

We're stumped. Has anyone ever run into a similar situation? If not and if you were faced with the same situation, how would you consider debugging it?

I have a site-to-site VPN set up with two SonicWall's (a TZ170 and a Pro1260). It was suggested to me that turning off encryption (so the VPN is tunneling only) would improve performance.
