Slow rendering using Syncfusion Grid

[FRANN LP]

We're loading 200k data rows and the browser stops responding, the stored procedure takes 5 seconds to execute.

Our code is based in the following example: https://ej2.syncfusion.com/javascript/demos/#/bootstrap5/grid/grid-overview.html .

Also we're using VirtualScroll / InfiniteScroll

Hi FRANN, 

Thanks for contacting Syncfusion support. 

By default, EJ2 Grid can show 200K rows with Virtualization feature without any performance issue. We also have prepared a simple sample with 200K records and 11 columns which is working fine at our end. Please refer to the below sample link for more information.

Could you please share the below details that will be helpful for us to provide a better solution as early as possible. 

1. Share the Column count in your sample
2. Share the full Grid code with its settings
3. Share the Syncfusion version you are using
4. Are you facing any script error?
5. Share the browser details

Regards,
