App takes long time top Open

[Vigneshvaran]

Whenever I try to open an app, it takes a long time to open. What could be the possible reasons?

[rittermd]

The first time an app is opened it is loaded into memory.  So if it is a big app with a lot of data it could take some time to load.  If you are doing a lot of calculations in the app that could slow it down.  If you are not loading a QVD file and are loading data directly that could slow it down.  It could be that you don't have enough memory on your server.

As you can see it could be many things.  If you share more details about your app and your situation that would help.

We are loading via QVD  files.  It is a finance App, where we are using some calculations. The size of the App is 670 MB.

A very simple way to check your server behaviour is to use the task manager :

1 - restart Qlik engine service in order to remove the cache

2 - open the task manager to supervise CPU and memory consupton

3 - open your app using any user

As Mark said, if the server is not the problem, it could be many causes. Try to share more details about this app.

I have this problem every time when a sheet in an app is taking forever to load, and I close the tab, and reopen the app, and it would take forever. But how can I just delete the session and start new again??? Or how to make the engine stop calculating the previous tasks...

Please use Document Analyzer to troubleshoot this. You can easily see which Objects are taking time to open, Which Fields are unused and which Fields are consuming more memory. Accordingly you can work on those Objects and Field, and your performance will be better.
