Dashboards are laggy in displaying real-time data
(At least on my system) I experience a laggy behaviour of dashboards. This becomes especially evident with the plot and lamp widgets in combination with the Demo Signals IC. It looks as if the values that are shown in the dashboard are only updated approx every second one bunch at a time (just my rough guess). Reasons could be:
- My system is too slow (unlikely because the laggy behaviour was not present some months ago on the very same system)
- My browser makes some strange things with the websocket data (Firefox 84.0)
- A bug in the data handling of VILLASweb that delays the processing for some reason
- Influence of running everything in Kubernetes; the time offset widget should grant us insight into the time shifts between local time and remote IC times
We should understand the cause of this problem and find a solution.
