[Snort-users] Snort performance

Unfortunately results for Snort 1.8 are unreliable since post 2.0 versions are MUCH faster (that's when the whole multi-pattern-matching algorithms thing came in).
Results for Sourcefire IS3000 are not directly applicable to Snort because, as you mention in your report, the Sourcefire sensor uses a custom packet capture driver instead of pcap library. A custom driver gives MAJOR performance increase, results for vanilla snort are not going to be anywhere near that good.
my 2 cents,
