Yea, some engineers created a ground-up rewrite of Snort called "Suricata" that was multi-threaded, and therefore faster than Snort, which is only single-threaded. Suricata then failed to show any benchmark where they exceeded Snort's speed, and they fail to mention that Snort works fine on multi-core.

It's one of those things "everyone knows multi-threaded is better than single-threaded", but everyone's wrong.
