Very slow external list based on SQL Server

Question

I am using SharePoint 2016 on premises. This is a new farm with installation done just now. I created BDC to fetch data from SQL Server view. That view contain less than 8000 records. Then I created External Content Type in SPD and applied a filter so it will fetch around 3300 records. Problem is when I load that external list in browser it takes 50 seconds to show those 3300 records.

Although the view contain more than 30 fields but at this time I am just displaying three field but still it takes a long time. Is this normal?

If I query that view directly in SQL Server then it only takes 1 second.

Both SharePoint and that SQL Server are in same premises and network.

How to speed up this process?

You can use the SharePoint 2013 developer dashboard to monitor the access process.

You can check which step used a lot of time.

Besides, you can also use the fiddler to monitor the Loading process.
