The default configuration of the X100 Server is suitable for a machine designated to run a database system, and optimized to exploit most of the available system resources.

The default configuration assumes a single Vector instance per server and a single active database with multiple concurrent queries. It also assumes all nodes used by VectorH have the same number of CPU cores and physical memory available to them.

If you need to use multiple instances and databases simultaneously on one server, manual configuration is needed. (For more information, see Using Using Multiple Databases.) Reconfiguration can also be useful on machines with little memory or if you want to achieve maximum performance for single-stream queries.
