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.

Storage Dimensions
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.
Computing Environment
To ensure optimal performance, use Source on a computer that meets the minimum System Requirements. Standard laptop drives are not recommended for optimum performance. Also, we suggest reducing what else is running on your computer. If you are using a server to run Source, ask system administrators to reduce the services that are running. For advice on optimising server performance, see these two microsoft articles: here and here.
Microsoft .NET version 4.6.0 has a performance issue that affects Source performance, particularly when saving projects. If you upgrade to 4.6.1, it will resolve the performance issue.
