We have some intermittent problems with PI Vision performance. A lot of the time performance is good enough, but sometimes it's much to slow (>30s).
Any ideas how to automatically and periodically measure the load time of a (set of) display(s)?
First of all thinking about which tool to use, but that might be the easy part.
Secondly it might be difficult to assess when a page is loaded completely? The display rendering (especially of custom symbols using PI Web API) is of course based on async calls. So how to know the entire display is populatd with data?
Or in other worlds: how to determine the user-perception of "the display is fully loaded"?
