Has anyone had any luck with Orient and large database?

I tried to use it with a 80,000,000 product database with about 60,000,000 updates a day (edges between sellers and products labeled by price) and it was unusable with the same sizing as a mySQL database that handled it easily.

It seemed great though. Especially since neo4j open source is quite restrictive (clustering is a commercial only feature not available in the OSS version).
