Hey Simon,Snort 3 currently has one thread per packet source, whether that be a network interface or pcap. You can configure that with -z or --max-packet-threads. All processing of a given packet is within the thread associated with its source. You can set CPU affinity for packet threads via the process module. The architecture will evolve over time to support hardware offload and elephant flows (too big for a single core).
Please keep us posted on your results or if you have any questions about tuning for comparison with Snort 2.

Hey all,I am writing an article regarding to Snort 3 performance and I'm having trouble finding a reliable resource on the current architecture. I saw in the Snort 3 documentation the difference in the packet processing but couldn't find out if you are creating a thread for each packet or several threads for detection.Thanks and have a great day! _______________________________________________ Snort-devel mailing list Snort-devel () lists snort org https://lists.snort.org/mailman/listinfo/snort-devel Please visit http://blog.snort.org for the latest news about Snort!
