Well, you have a fifteen second delay in there... that might slow it down
Sounds like what you need is an event-driven communications driver
rather than a pull driven (http) one....
that way, you can get any changes as they happen from the host
only when the xml file on the host changes.
and then you might try adding some quick diffing code so that you can quickly
detect changes once they've arrived. And only process the updated regions
rather than the whole lot.
What you are talking about sounds pretty much like a realtime inventory
updating system. Just guessing..... but it sounds very familiar.
Another way is just to buy an off-the-shelf realtime inventory updating system
and then stick the triggers in the database on the product records.
Everything you need will be done for you, and you just write the code for
after the product items have been changed.
ahh... the wonders of black box componentry.....
just a thought.....
