App opening in hub very slow (qlik sense enterprise version)

[Anonymous]

Hello!

Could you please suggest some ideas on following issue:

If any user (including administrator) try to open sheets in QS Hub, they are uploaded for at least 3 minutes, regardless of the size of the application.

With what it can be connected? And how to fix it?

Thanks in advance,

Kristina

Hello, 

There are multiple factors that can impact and most of then would related to the environment and/or the setup.

Here are a few steps that hopefully will help you:

• Is it only when opening a sheet? If yes, there was a defect identified in Qlik Sense June 2018 and September 2018. A fix has been delivered in Qlik Sense November 2018. See First Opening of a sheet in Qlik Sense Enterprise is very slow
• Has it ever worked before? If yes, any changes (More users, more apps, new hardware, upgrade,...)
• Have you tried locally on the Qlik Sense server using https://localhost/hub?
• Is Qlik Sense running on a Virtual Machine or Physical server? Please see 
  • Virtualization Best Practices in QlikView and Qlik Sense
  • Server Hardware Whitelist  From Qlik Scalability Center
• Have you tried to check the CPU and memory consumption at the time you experienced the issue to make sure your server is not overloaded?

Hope this helps.
