I got surprisingly good results when changing the _id design. I advise
you to follow what is written in this page :

Basically :
- use shorter _ids
- use sequential _ids. If you cannot (eg because you have multiple
disconnected parts that will have to merge often and that would cause
too many clashes), you can use couchdb's own semi-sequential generated
uuids. Yes, uuids are contradictory to the first point.
