Intrusion Detection Help

[Julien]

Dear All,
Today we have installed a OPNSENSE Hardware behind 1GB internet speed.
after we enable the Intrusion Detection the speeds drops from 1GB to 80MB/S
is this a normal behaivor ? if yes is there is a way to tweak the speed?
thank you guys

I would expect there to be some performance hit, depending on the specs of the hardware you are running OPNsense on, but not that big of a performance hit, what type of NIC are you using on the WAN interface? Also, what are the other hardware specs?
