[Snort-devel] Performance issue in 2.9.8.0

Hello,

I've noticed that the memory profile and performance of snort 2.9.8.0 has
drastically changed in 2.9.8.0 over 2.9.7.6.  I run a large PF_RING enabled
sensor running 20 sessions of snort in 'AC' mode (to maximize performance)
and each snort session now seems to consume nearly 4 times the memory of
the previous version.  After running the two on the same sample file, I
found drastic differences.

I've attached the full runs of each to this message, but to summarize (two
runs on the same sample pcap).

2.9.7.6:

So while I concede it did find 40 extra alerts, its created a situation
where I can't run as many snort instances without buying significantly more
RAM nearly halved my packet throughput for each instance.  If I run my
typical configuration with 2.9.8.0 in production, I can't run 4 instances,
the CPUs on the remaining instances are pegged, and nearly 40% of my
packets fall off my ring unprocessed.  That just doesn't justify 40 more
alerts IMHO.

I was going to submit this as a bug, but its not really a bug if the
intention was to close potential gaps in the packet processing stream.  I
think people just crossed the 80/20 rule.  If someone from SF wants to
weigh in publicly or privately that its a bug and I should go down that
road, let me know.

I have not repeated this test in other pattern matching modes because the
performance curve drops as many packets, if not more, in my production
configuration.  Others might have the same findings if they are not running
such a saturated link.  There seems to have been tidbits on the mailing
list about dropped packets in 2.9.8.0 without much investigation behind
it.  I might be mirroring those findings.

Thanks,

Phil
