Measuring the performance of the Presentation Layer

In the previous section, we found out that OmniScript time tracking simply records the time a user spends on the step. So, for UI steps, we used a simple LWC to immediately advance the user to the next step so that the step loading time can be recorded.

This approach worked well for the internal OmniScript components we were testing in the previous section (Performance impact of the OmniScript best practices). Now, what if we need to measure the performance of a step with UI controls that also take time to load? Let’s look at an example.

Let’s say we have a FlexCard on an OmniScript step and would like to measure how long it is taking to load. Let’s use the sample OpportunitiesCard we used in Chapter 2, A Sample Application. This card displays the list of Opportunities in a specified Account:
