Timesten - Query

1 - Parallel

Timesten 11.2.1 doesn't support any form of parallel query. TimesTen will then execute this query single threaded (ie with a single CPU).

Even if an Oracle database has to go to disk, it will perform a parallel table scan and aggregations with a bigger speed-up than a single threaded TimesTen (without taking into account the table size difference).
