CFFORM flash remote call performance

I have a CFFORM flash format that's being accessed from a remote location. This form invokes a cfc through actionscript, and updates input fields in real time. Locally, within our intranet, performance is excellent, but remotely, everytime, the data takes exactly 30 seconds to show, no matter what the component returns, error or otherwise.

Anyone have any suggestions why this would be happening?
CFMX 7.0.2 on win2003, iis , xeon dual, 2gb ram.

THanks a lot for your help.
