I am working with 5,600,000 rows approximately and I've been extracting data to excel files since 1 month and it was easy and quick but now, the same data extract has a lot of time near of 2 hours to give me only 600,000 rows and i dont know why it's soo slowly.
Is there any way to clean some cache or refresh my .qwv to try to improve the speed for this extraction. Suddenly this proccess turns slow.
