Re: 2.1.3rc1 Performance

Hi Gary,
Yesterday I replaced my 2.1.1RC1 build with 2.1.3RC1. Today I checked the perfmon stats and nearly fell off my chair. They are reporting that snort is dropping on average about 15% of traffic. With 2.1.1RC1 perfmon has always reported 0% pkts dropped and I believed it. Now I am seeing that there are times when snort is dropping as much as 89%, and that is at times with only 0.9mbps throughput and using 11% of the cpu. Some other times i am seeing drop rates of 12% with 5.1mbps throughput while using 77% of the cpu.
did you use the same rules on both versions? There are a lot of changes between these two versions especially an increase in the use of pcre... And did you also use the same libpcap?
