Hello Elver Emilio Cano Cardona,
Thank you for writing.
You are using lots of appointments and that will surely decrease the performance. However, I am not able to observe that big loading time (6-7 minutes). In general, you can use the BeginUpdate
methods of the Appointments collection of RadScheduler
if you are making lots of updates at a time. However, I am not sure if this will fit in your case. Therefore, I would kindly ask you to either open a new support ticket and send us a sample project which demonstrates your scenario, or post your code here on the forums. This will let me investigate your case and provide you with more a concrete answer.
I am looking forward to hearing from you.
