Recently I changed StaticDisplayLevels from 3 to 5 in MasterPage of SharePoint Online.
Due to this Response time of page drastically increased from 15sec to 56sec (Big Difference).
Could anyone explain me why?
the StaticDisplayLevels property is to specify the number of menu levels to display in a static menu. All menu levels below the specified value are displayed in a dynamic menu. Since you are increasing the number of menu levels to display it is taking more time to load and hence more response time.
