Polling rate of 60s (or frequency of 1/60s) results in extreme unresponsiveness

[MatthAlex]

Issue

Started an experiment with a polling rate of 60s, which ran for 2+ days.

The UI controls, tabs, export functionality, all felt very sluggish throughout.

key observations

• This experiment and stress test used the exact same setup; RPI4 + ADC
• polling rate of 60s is 30 times less data points than the 4.5 day stress test
• stress test's UI and functionality was usable through the first 2 days
• approximate number of points is <5k
• initial test with downsampling (iloc 1 every 10 points) worked very well, with around 17k points
• 60s poll rate was not tested for usability; may be a particular bad configuration

Possible Explanation

The call to the device is blocking; the linear execution of the app may result in slowdowns on every piece of functionality.

Possible Solution

Investigate async/await for the device calls.
