The Users are Opening/Using "Other's Calendar".
There are five Calendars that they open, however two are only used weekly.
The five Calendar's give everyone view(reviewer) rights.
The Scheduler has Owner rights.
Normal Searches (Finds) values are firstname and/or lastname which were
created in Subject field.
Advance Finds with Subject equals firstname and/or lastname.
Sometimes additional criteria "Start" On or after Date.
Usually only one person creates or edits appointments and many search/view
Calendars.

Could it be the number of appointments (items) in the Calendar?
Or the number per day?
The three busier Calendars have 6,000 to 14,000 appointments.
They like keeping at least three months in the past.

Unable to reproduce it - what search criteria are your users specifying in
the advanced search? I use "created" and "today." Search is instantaneous.
