Performance Issue with Two Scheduler Partners – Slow Drag & Drop and Interaction Delays #9882

Forum post

Hello team, I am experiencing significant performance issues when using two scheduler partners in my application, especially when dealing with a large number of events and resources on both schedulers. Here’s a summary of the problems encountered:

Details: The drag-and-drop action between the two schedulers can take several seconds to complete, which becomes more pronounced due to the large dataset. Zooming in and out or moving to different routes results in delays, significantly impacting the user experience. The issue occasionally leads to the application freezing, requiring a refresh.

Expected Behavior: The drag-and-drop functionality should be smooth and responsive, even with large datasets. Other interactions such as zooming and route navigation should not cause delays or freezes.

Please let me know if further details are needed to diagnose this issue. Any help or suggestions for optimizing performance in this scenario would be greatly appreciated.
