[Snort-users] packet loss

If you have plenty of cpu and  memory I am assuming you are not page
faulting, in which case you might just need to use the mmap version of
libpcap. It uses less cpu than the standard pcap, but also has much less
packet latency during sniffing so it does not drop as much.

Subject: [Snort-users] packet loss
 
In the course of my testing of Snort I have averaged about 40% packet
loss. I am running Snort on Fedora. The segment I am monitoring is 100
mb and is very busy. Does anyone have any recommendations for tuning
Snort to not drop so many packets? Is there any recommendations for
hardware? The CPU is running at about 40% and the memory looks fine.
