Sure, many tests are conducted in a wrong way, I fully agree. About multi-gets, this is how Redis handle this, we have a concept called key tags, that I think it is very similar to the one you described. Basically a key in the form foo{bar} gets hashed in a special way, only the part inside {} is hashed ('bar' in my example). So a client willing to optimize for multi get will use {user0}:name {user0}:surname and so forth. Well, not the perfect example as with Redis in this specific case you could use an Hash that is much more space efficient and will provide locality of related keys automatically.
