I enabled more detailed logs and our read-only trend display now pauses while the folder is busy. The cell controls are separate. What should we measure before deciding the file writes are to blame?
We once chased a supposed connection problem from a screen that was simply behind. I'd ask the developer for separate receive, write and display timings. Folder activity and a stationary screen are observations, not a completed diagnosis.
Anil's question is worth answering before changing the design. I'd also establish what the trend must preserve, so a proposed faster display doesn't quietly throw away the samples the diagnostic record needs.
Have the maintainer own that comparison and the recording requirement together. A screen that looks lively while its useful history disappears would be a poor trade, even if it stops this particular complaint.
