My site might have a lot of events. How many would be too many in terms of the performance, especially when multiple events owners are editing events at the same time? Right now I can see a noticeable performance decrease when there is only one event being edited.

Hi,

it really depends on the hardware infrastructure such as processor, and RAM, as well as the network connection.

For the module, we do not have a limit on the number of events you can have.
