Thanks, we'll try to reproduce the issue. Re: your question, statistics is built when you load a fresh database with `db create` and optimize it later after updates with `db optimize` (though it can be disabled for the latter with `-o optimize.statistics=false`). If you simply start the server, it should not rebuild statistics.

I must add, however, that selectivity statistics is the main source of information for the cost-based query optimiser so disabling it like that may have negative effects on query performance.

Cheers,
