Maybe you meant to reverse those small/large.. The biggest difference between smaller and larger packets as it relates to snort and libpcap is really the interrupts it generates. At 20Mbps with large packets, most systems can handle that... but if you pump 3-4 times the packets down the pipe, you're likely to see drops and livelock. In snort 2.x user CPU doesn't ever appear so great as to cause a problem in either scenario. -----Original Message----- From: Mehmet Ersan TOPALOGLU [mailto:mersan () ceng metu edu tr] Sent: Monday, August 25, 2003 6:27 AM To: snort-users () lists sourceforge net Subject: [Snort-users] packet size In case of constant, for example 20Mbit/s rate, network traffic. What is the difference between large packets and small packets for snort and for libpcap? e.g: first case: large packets -> 5000packet/s with 20Mbit/s rate second case: small packets -> 20.000 packets/s with 20Mbit/s rate -- - mersan mersan () ceng metu edu tr mersan () metu edu tr Budi srecna.
