Given competing claims, an objective head-to-head comparison of the performance of both snort and Suricata Intrusion Detection Systems (IDS) is important. In this paper, the authors present a thorough, repeatable, quantitative, apples-to-apples comparison of the performance of Snort and Suricata. They compare both the default, \"Out of the box\" performance of both systems and investigate alternative configurations such as multi-instance Snort and improvements to Suricata that were inspired by their initial results; changes to Suricata inspired by their testing resulted in performance improvements of up to 20X.
