Problems loading data from impala.

Hi support,

we are having problems with an application that is taking a very long time to load data from impala.
From checks made on the machines, we did not find any particular Error or Worning reports.

The application takes about 20 minutes.

When opening the app from hub, it only loads from qvf.  So the performance is not related to data reload backend. 
To investigate this app performance, below methods can be helpful.

1. open the app directly from your Qlik Sense server and see if the performance is network related. 

2.Open telemetry dashboard to see if there are special objects take longer time to open. 

3.If qvf dataset is quite large. 

4. Check the app to see if there are many front end expressions defined.
