Introduction
A profiling tool was developed in Source to help that the modeller assesses where the running time is being spent. The function of this tool can lead the development of more computationally efficient models and is a complement to speed improvements.
...
This tool was included in Source version 4.4.0 - Beta Release (May 2018) and Source version 4.5 - Production Release (June 2018) and will be in any later Source version.
Access the tool
The model profiling tool is available as a recorder. It can be found under Miscellaneous \ Performance \ Scenario Model Timings\ in the Project Hierarchy, shown as Figure 1. It can produce a report that shows the execution time per component (e.g. node, link, catchment) and per phase (e.g. flow, constituent, ordering. etc.).

Use of the tool
The user can use this tool to find which areas in their model take the most time and then see how to improve the model runtime.

The user can see detail of every phase or every element in every phase.
