There are several user-configurable options in Source that can be used to increase performance (ie. reduce model run times) by changing the way Source runs the model. Many of these options will be suitable for the majority of models, but they can cause changes in results for some users, so caution should be used when selecting them.

To turn off all recorded parameters, in the Project Hierarchy, right click on the scenario's name and select Record None (Figure 1). Navigate to the parameters of interest using the Project Hierarchy and Parameters pane, right-click on the parameter and choose Record All (Figure 1). For more information, see recording parameters.

Parallel Networks
Networks with multiple outlet nodes (Figure 2) can be configured to run separate networks simultaneously by selecting Run Separate Networks in Parallel (Figure 3). This should not be selected as an option if there are calculation dependencies across the separate networks, e.g. Subnetwork 2 calls a function which involves a value from Subnetwork 1.

Components of a model can be deactivated by right-clicking on them in the either Schematic Editor or Geographic Editor and choosing Deactivate. Deactivated nodes are indicated by a grey circle backlash symbol on top of the node icon. Deactivated links become a solid grey line. (Figure 4). . In Geographic Editor, deactivating a link will change the border of its associated sub-catchment to grey.Deactivating large sections of a model (eg. a network branch) will improve performance by decreasing model run-time. This can be useful when you are working with part of a model only, eg. during calibration.
