How do I tell what freezes our separate UR5e trend display?

Detailed logging is enabled and our monitoring laptop sometimes stops updating while the folder is busy. Cell controls are separate. I suspect file writes, but I have not measured the read or screen-update time. What should I ask the developer to compare?

Have them time the read, file write and display update separately, then exercise controlled delays in each offline. Folder activity is a clue, not enough to choose a repair or a replacement laptop.

The first timing run showed long display updates as the chart history grew. File writes were short in that run. Developer is checking the chart and repeating with a deliberately slow writer.

Do fresh readings still arrive while the chart is stuck?

Yes. The stored readings keep their normal sequence while redraw gets slower. A bounded visible history fixes that in the test version; the full recorded history remains available separately.

Then keep the two histories clearly named. Also test a genuinely delayed read and the slow writer, so a responsive chart does not imply that its latest value is fresh or every reading was recorded.

Developer tested both delays and the recording limit. Display age and recording-gap indication remain separate. Installed read-only comparison ran through the normal session without the growing redraw delay. We closed the chart issue and kept the timing evidence with the handover.
