This was the capacity in 2012 and I don't think Baggage reclaim would have changed since then
Process Element Capacity (pax/hr)
Departures
Check-In 2,350
Central Security 2,630
Arrivals
Immigration 1,810
Baggage Reclaim 1,370 International
Baggage Reclaim 250 Domestic.
As can be seen it was the airports weak spot but less people check luggage in these days.
