In one embodiment, a monitoring process detects a page load start time of a single page application (SPA) page having added direct resources and dynamic resources, tracks the direct resources and dynamic resources, and notes a load end time for each of the tracked direct resources and dynamic resources. The monitoring process stops the tracking of the direct resources and dynamic resources in response to a determination of a threshold duration of network inactivity, and determines a maximum load end time of the tracked direct resources and dynamic resources. Accordingly, the monitoring process may then set a page load time of the SPA page as a difference between the maximum load end time and the page load start time.
