Hello, I am working on a generic OData provider to go against a custom data provider that we have here. Thsi is fully dynamic in that I query the data provider for the table it knows.

I'm new to WCF Data Services so I've been playing. After some initial tests I am disappointed by the performance of my test data service. I realize that because a WCF DS is HTTP-based there is overhead inherent in the protocol but my tests are still way slower than I would expect: Environment: All on one box: Quad core 64-bit laptop ...
