What exatly happens when an app reload

We are facing a performance issue with our qliksense deployment. our reload is every hour and the problem what i identified is that, after every reload the very first user facing more initial loading time like, 20-30 seconds and for the subsequent users the app loads less than 10 secs. 

Note: we are performing incremental load but not full load

The question here is, is qliksense removing the data from memory for every reload? If so then how do we overcome this.

Also we tried to implement the Cache warmer solution but the experience is still same. - App Preload/ Cache Warmer.

Any help would be really helpful.

Hi Microland,

This very common and the reason for this is because the data is completely reloaded. The model is not in memory at that moment, it just sits on the server, waiting to be called. When your first user opens the document, it's just like opening the document on your local Qlik Sense Desktop, this takes time of course.

In QlikView it was possible to preload applications, especially when they were big, like >10GB. But sadly, this is not possible in Qlik Sense Enterprise. Even buying a tool is not working.

The only thing that you can do is opening all the apps before users login. It should be possible to code this that this happens automatically.

Its probably not the answer you wanted to hear, but this is it!
