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.

Water User Orders
Orders generated by water users were previously calculated sequentially from the bottom to the top of the system. As of 3.8.18beta, Process Water User Orders in Parallel is enabled by default, which means that orders are generated simultaneously within a timestep and passed to the supply points. This will decrease model run times.

When configuring a storage, give consideration to the number of points used to define its dimensions, and use the minimum number of points necessary. minimise the number of points used to define its dimensions. The more points there are, the greater the processing time during a run.
Audit Log
The audit log keeps track of the changes made to a project over time. This is particularly useful for projects that are worked on by multiple people over a period of time, but can become a processing burden, especially in the case of large projects. It is now possible to disable and clear the audit log. Access this option through Edit » Project Options.
