Performance!
In my MIX talk I told that for 2k reads, we take 3ms. It is actually the case under load where the servers are straining. Here is a latest performance shot that we got with the CTP3 bits.
Bulk APIs: Note that these numbers are without any bulk operations. With bulk gets (we are trying to add a Bulk Get in RTM timeframe within a region) we get upwards of 211,000 operations per second. (assuming a 32 key per batch).
Local Cache: None of these tests use Local Cache = true. That will again give upwards of 200K operations per second.
[Statutory Warning: These are the numbers that we got in our test labs to give you an idea of the performance characteristics of this product. There is no implicit warranty or guarantee on these numbers!]
