Do I have a way to increase Scheduler performances ?

[Julien Gambini]

Hello,

I am using the Syncfusion Scheduler to display a timeline of production events. I am using the datamanager with ODataV4 to get the data to display. You can find the code of the view in attachment.

The datamanager is getting arround 3000 events in a day (the OData API takes about 1 second to answer the request). I can notice that the display of events takes much longer to display the data (as you can see in the Animation.gif in attachment). Several things :

• I don't understand why when I'm clicking to change the current date, the Scheduler is freezing for 8 seconds before to start loading the data ?
• After that, the Scheduler is loading for 12 seconds (I guess to make the rendring of the big amount of events). Is there a way for me to reduce the time to load the data ? Because depending on the client computer, it can be very long.
• Maybe I'm using the wrong component to do that, and maybe I should use another Syncfusion component ?
