Gantt Chart load is too slow

Hello

My Gantt chart extracts data from SQL Server, which has approximately 500 records. However, it takes around 16 seconds to display the data. Is there any way to improve this issue? I am using PHP and the database is SQL Server.

The image below shows the messages in my console. The DOM mutation listener is running one by one, and all of them need to be completed before displaying.

Has anyone this question?

Thanks

Hi


Thank you for reaching out to us with your concern regarding the performance of your Gantt chart while extracting data from SQL Server. We understand that this issue is causing inconvenience to you.

You can see in the console log that it doesn't take much longer to render the Gantt chart than the video we've provided, which shows 600 records being rendered.

If you still face the error we suggest using virtual scroll which will allow you to load large amounts of data without performance degradation. This feature can be implemented in your Gantt chart and can significantly improve the performance.

You can find more information about this feature and how to implement it in the UG link provided below.
