Reloading time after applying filters

[Venkatesh_Yellu11]

In the Qlik sense to load entire data from the QVD's it's is taking 15 to 20 minutes for 2 years data, but loading one day data taking same time 15 to 20 minutes why ? After apply the date filter
How to reduce load time for one day .

If there no difference in loading time for one day data and 2 years data then why should apply filters for reduce the loading time

If you can give sample of load script, they would help us, help you.

How you do the QVD filtering matters. You don't want your filters to break the optimized Load. See https://qlikviewcookbook.com/2026/02/optimized-load-script-patterns/

Other reasons to load only the data you need is run time performance and capacity.

@rwunderlich  We observed that when the same filters used for QVD data extraction and are applied directly to the source, the data loads faster than when loading from QVDs
