Jon,

Yep, a subset will keep you from falling behind and loosing the
"important" data. After one falls behind an hour the LDM skips products in
the queue. Also, if you only request a subset then the ldm can take more
tries to get the products. If you are not using the HDS model data, make a
filter to eliminate it. The model data is large.

Other sites have worked with their network people or ISPs to get the
service/bandwidth that they need. If one keeps requesting/sending trouble
tickets the service will improve. The squeeky wheel approach seems to
work. I can't  really do anything because I'm not a customer.  When the
problem is the worst contact the people and then demostrate the problem.
