You may want to try BPF in zerocopy mode to test performance improvements: sysctl -w net.bpf.zerocopy_enable=1Don't forget to add net.bpf.zerocopy_enable=1 to /etc/sysctl.conf
BPF is for PCAP mode (non-IPS). It doesn't hurt to try this setting, if it brings performance gains, but can also be safely ignored.
Upgraded from 17.1.11 to 17.7 and Suricata 4.0.0. Went smoothly, no issues. apu2 AMD GX-412TC SOC (4 cores)
