When QlikView finished reloading, it has to build the Data Model. The process of building the Data Model sometimes takes time depending on the number of joins / associations QlikView has to create.
If it takes long to then you need to look at your code and see how you can optimized your application.
As there's no QVW file attached, there's no way to suggest how to optimized your application. However, there are several way to do this. If you need further suggestions from community post sample file.
Hope this is helpful
do you have so many joins keeps synthetic tables circular references etc ?
do you have section access getting loaded after the script which is complex ?
what is the server configurations ?
what is the physical size of the file ?
it would be great if you can generate log file and share it for better understanding
