# Initial Node Installation Defaults

By default, the Tableau Server installer configures the number of process instances that Tableau Server runs based on the hardware detected by the installer. The default configuration applies to single-server installations and to the initial server of a multi-node installation.

You can calculate the default configuration based on the following rules for each process, where the "number of cores" refers to the number of physical processors:

| Process Name | Number of Processes |
| --- | --- |
| VizQL Server | Equal to the number of cores divided by four, up to a maximum of four process instances. |
| Backgrounder | Set to two unless the number of cores is fewer than eight. |
| Cache Server | Set to two unless the number of cores is fewer than eight. |
| Data Server | Set to two unless the number of cores is fewer than eight. |

For all other process types, the number of process instances is set to one, regardless of the hardware.

Here's an example default configuration for a computer with 16 cores:

| Process Name | Number of Processes |
| --- | --- |
| VizQL Server | 4 |
| Application Server | 1 |
| Backgrounder | 2 |
| Cache Server | 2 |
| Data Server | 2 |
| File Store | 1 |
| Data Engine | 1 |
