[Bug 1294607] [NEW] [saas-3] Event: Perfomance issue when loading an event list with a huge amount of registrations

 

Public bug reported:

The loading of the event list in marketing/event or in
reporting/dashboard/event listing one or more events with 50.000
registrations takes at least 20 seconds by event.

The problem comes from the event calculated fields (seats_reserved,
seats_used, seats_unconfirmed, seats_available, seats_reserved).  Those
fields are not stored and are calculated each time a list is displayed.

Also even if the list displays only one of those fields, all the fields
will be calculated anyway in the function _get_seats.

Tested with Chrome on saas-3.
