Thanks for the answer.
Here are some more detail about the hardware (it's an Intel card).
I have done this modification in the file
"/boot/loader.conf"
#
#Increase the memory allocated for the network card
#driver. Useful/necessary to take in account
#the 4 network card (instead of one).
#See this link:
# https://docs.netgate.com/pfsense/en/latest/hardware/tuning-and-troubleshooting-network-cards.html
#for some explanations.
