When you increase the number of pages with referenced properties, the time taken to render the report increases exponentially.
Response is 1.72s from the space and ~2 seconds to render the report successfully.
Response is 5.85 seconds from the space and 6 seconds to render the report.
Response is 15.5 seconds from the space and 16 seconds to render the report.
To improve this performance could a cache of the results be saved and be referenced before reload. Alternatively could the delta between content additions be referenced instead of the entire space?
This behaviour has been replicated on multiple instances.
