We shard out to 1 SQLite database per user's working session, so there really isn't a meaningful figure if you are looking for apples-to-apples in a traditional sense.
Our most heavily loaded SQLite instance probably sees 100 writes per second. In aggregate, we can handle tens of thousands of requests per second.
