How can I improve performance of a materialized view with order by clause?
I've created a materialized view with ~57 million rows. When I query using an order by, it takes ~12 seconds, but without an order by, it takes 200msec. Is there anything I can do to improve performance when using it?

- Check the deployment setup and the number of CPU cores being used.
- Analyze the query being executed on the materialized view.
- Ensure proper indexing on the columns used in the query.
- Consider optimizing the SQL query by selecting only the necessary columns.
- Monitor the query performance in different environments (e.g., C# and DBeaver) to identify any discrepancies.
- Warm up the block cache to potentially improve query performance after initial slower executions.
