    Description

      Hello,

      after we upgrade from 3.4.14 to 4.0.1 we have noticed that the widget "problem by severity" takes very long time to load.

      We have done deep checks on systems performance and we haven't found nothing relevant. The CPU, memory and network statistics don't show any spike or overload.

      We have performed some analysis on the client browser and we found that it takes about 2 minutes to execute a POST of 144MB. Most of this time the browser is in idle state.

      We have tried to create a test dashboard with only the widget "problems by severity" and then load the page with debug mode enabled, the result below:

      ******************** Script profiler ********************
      Total time: 111.188555
      Total SQL time: 42.166975
      SQL count: 1519 (selects: 1138 | executes: 389)
      Peak memory usage: 521M
      Memory limit: 8192M
      

      Steps to reproduce:

      • Upgrade to 4.0.1
      • Login and wait the main dashboard to load

      Result:
      See screenshot attached

      Kind Regards

      Vittorio
