Performance of Gantt Chart in WebAssembly Render Mode

Hello Syncfusion Team,

I have noticed that there is a huge performance gap between Server and WebAssembly render modes for the Gantt Chart component. Specifically, the simple action of selecting a task can take about 5 seconds when you have 500 or more records in the Gantt Chart when using WebAssembly.


I have tried using RowVirtualization and TimelineVirtualization to speed up the Gantt Chart, but it is still not meeting our speed and performance standards (It still takes about 2 or 3 seconds to select or deselect a task). It's even longer than this when you try doing a bulk-select action, such as using CTRL A to select all tasks in the Gantt or SHIFT Click to select tasks in a range.


What might be the reason that running this on WebAssembly is causing this large amount of latency on the component? Is there anything that can be done to resolve this?

Thank you.
