I tried writing a function that could perform the filter operation,but evet though the queries dropped to 7k, loading time has increased drastically.

I am trying to optimize some queries for data visualization. Currently I have 12k+ queries, because I constantly filter on a bigger queryset. I tried writing a function that could perform the filter operation(as django apparently queries the database for each filter call), but evet though the queries dropped to 7k, loading time has increased drastically. Anyone ever dealt with this problem?
