| are you doing this on every request to your site, or only at a given
interval?
my site has an article entitled 'grabbing a slashdot feed from ASP'
which shows how to grab a feed only at intervals. you could stagger the
intervals at which the ten sites get scanned so that any one page hit
will only get the three second delay, I suppose.

Do what Atrax suggests: periodically pre-fetch the information from the
10 different sites and store that part of that information you need in:
- Application variables, or
- a database, or
- file(s).
This pre-fetch can be done by a non-ASP program (e.g., a VB program that
is scheduled to run every minute or so) or a Windows service.
When your ASP page receives a request for information, it can
_immediately_ build a response from the pre-fetched results. Your users
will experience no delay whatsoever.
Good Luck,
