When a user clicks the View button on a lead record, the modal takes approximately 14 seconds to open and display data.

Our investigation shows that this does not appear to be a database or API issue:

The API request to /api/data-queries/{id}/run?mode=view completes in approximately 800ms
Response payload size is only 1.5kB
The same SQL queries execute directly in MySQL in less than 20ms
Server-side pagination is enabled with 20 rows per page
Total dataset size is approximately 2,944 records
Based on the Network tab, the data is returned quickly, but there is a significant delay before the modal is rendered on screen.

We have attached:

Could you please help us investigate the cause of this rendering delay? This issue is significantly impacting the usability of the application.

Thank you for your support.
