I'm using tableau with a bigquery data source that has 500M rows, 30 columns. In order to have this BQ data used by my workbooks I refresh an extract (hyper) every day.
In my workbooks I have 6 parameters and one filter that is a user filter. I notice that the workbooks loading time is slow. It gets also slow when I change the values of parameters. When using performance recording I get numbers of 40s per query. While reneding time is in the order of milliseconds.
Is this normal even if I'm using extracts with less quick filters ? How could I enhance the performance of querying ?
Tableau Server info : I'm using Tableau 2022.1 on a 2 nodes server with 256Gb Ram.

How many marks are you pulling into the Dashboard? If it is a summary query /Dashboard, it shouldn't take this long. More the number of marks you pull out, higher will the time taken. Also, user filters could also be a problem. Try removing that to see the impact.
