I have response time problem with the backend tab "Events".
Example: Creation of an event in the backend.
1°/ When I click on date field, the datepicker spend 4 or 5 seconds to appear and after the date selection, it spend 4 or ( second to close the date picker and filled the area with the date.
2°/ When I want to filled the adress (PostCode, City...). I have the same problem. After taping, the system need 4 or 5 second to filled the field.
Does anyone know how can I improve the response time ?
