Look forward to your reply,thanks!

How much CPUs and RAM are assigned to Suricata?
Also update to a more recent stable version, 6.0.3 is rather old.

Thank you for your reply. 8 cpus and 32G ram to Suricata. Suricata can carry 1.2g network traffic after testing.Looking forward to your more insights

How does the htop output look like if the traffic is there?
Did you update to a more recent version?
You could also run perf top -p $(pidof suricata) to see if there is anything to spot;
Ideally post the suricata.log and/or the output when you run it to check if there are any hints/errors.
Another idea would be to try AF_PACKET to ensure it’s not related to PF_RING

Seems to be a performance issue.



suricata.log

It seems you are running with profiling enabled

Profiling enabled:                       yes

That will affect performance for sure.
If this is production , you should not enable the profiling.

Awesome!:+1:
In fact it is,have obvious effect,1.4g/s drops count::0%
Thank you very much for your reply
