Suricata losts many packets when no rulesets are loaded

Hello team,

I met an issue in our project which is very weird and hard to explain, really need your help here!

We are using suricata 6.0.13 currently, preferring af-packet mode and ET Pro signatures. In our first use case, we were loading no ruleset (empty file suricata.rules ) at all and then replayed pcap files with different speeds and recorded the statistics with suricatasc (unix socket) , when the speed came to 100mbps, turned out Suricata lost about 40% of the packets. After which ET Pro signatures (about 40000+) were loaded we tested 100mbps again, no packets is lost

Is this the design logic in Suricata or am I using it the wrong way? Thanks a lot

This is the configured suricata.yaml (sorry it’s too big to post)
suricata.yaml (76.6 KB)

How exactly do you do the pcap replay?

How do you run suricata?

Please post suricata.log and stats.log for both cases.

The drop rate without rules being higher as with rules is not expected.

OK, unfortunately I lost some logs. I got some retest log with loss rate 1% on that platform

Here is the log when no additional rulesets were loaded
