Performance issue in app

rajendra1918 — Mon, 26 Jan 2026 18:19:17 GMT

Hi Friends-I have a query on performance related in Qlik app.

I am using windows 2012 R2 server with 16GB RAM. Facing slowness in one of the app.

App size is 1.5 GB , it is always showing me buffer status of any one visual is clicked. How can I improve my app performance ?

Please share you ideas/suggestions.

Regards,

Rajendra

That's not much information about your data model, charts and expressions used etc.

Hi Rajendra,

One quick thing that you can do is try analysing the unused fields in the dashboard and try removing them which could save huge memory in my experience. you can use document analyzer for that purpose.

Identifying Unused Fields With DocumentAnalyzer | Qlikview Cookbook

Try removing the historical data which the user is not really care of.

Ofcourse, the above thread by Stefan as well will help a lot.
