Ireland does not require transit passengers to clear Irish immigration. Passengers will simply have to deplane, head through US immigration and then reboard. No hold bags need to be unloaded as customs can be gone through separately in NYC. The wait time for bags is likely to be short as the amount of checked baggage will likely be low.
The US is unusual in requiring transit passengers to go through US immigration.
