Who is the T1 provider? Who is the DS3 provider?
Is it a full DS3 or frac? What router do you have? Could it be configuration? Could it be that you bought a DS3 from a provider with either a lousy network? Or maybe just bad peering/transit with the place you are attempting to download from? A DS3 is not a DS3! Consider if your provider of the DS3 only has an OC3 network for you to use and has it oversubscribed 4:1? Would that work well? What do GRE tunnels have to do with anything? Describe the network. Give more details and a better explaination may come.
