From my home, inserting a document into DocDB requires about 200-400 ms after connecting. Connecting seems to require about 2 seconds alone. I know it's on the West coast, but still... I think it will connect faster when I'm within the data center. Code could also use some async optimization. Serilization might also eek some additional gains. Excited to get this in the data center and test out the throughput. Documentation specifies 500 insert/replace/delete per second (http://azure.microsoft.com/en-us/documentation/articles/documentdb-manage/).
