Likewise. I started some stuff at work recently comparing Mongo, Orient and PG (using a JSON column). Alas, all the test suite does so far is insert small "documents" (5000 docs w/ 3 name-vals excluding PK/ID) and time that. No read-back tests of any kind yet, so no indices in place either.
For this little test (on my macbook), Mongo was the fastest. PG took 1 1/2 times as long, and Orient took 4 times as long as Mongo. All 3 were driven by a Java client connected via a socket to the DB on localhost. (Orient could have been "in process", but I wanted it external as if on a server)
Of course, the main use-case for Orient is reading back graph chains, so it's a horrible test. However, what we need is a supplemental store to dump some flat junk as the app runs.
