There is still a single lock per db.

There is still a single lock per db. It also uses huge amounts of space (around double JSON of same data). That puts increased pressure on memory. It also has no usable compaction. And can be rather dumb with indexes. ( note ) The main mongo solution for things is to run lots of copies of it across many machines each with small chunks of data. In theory what is then a pain point on bigger systems becomes lots of lesser pains on small systems. ( note ) every criticism is answered with how the next release will improve things. Sometimes that happens.
