I've been using Squeeze libpcap (ie. 1.1.1) to capture some traffic from a gigabit ethernet adapter today, connected straight to another gigabit adapter of another host that was sending a pcap file with tcpreplay. receive buffer was resized up to 60Mb (with proper rmem_max). And I also experienced a huge packet drop whenever the throughput raised above 50MB/sec (up to 100MB/sec). By huge, I mean almost 50% of total received packets (ie. one third of the packets were lost according to pcap stats). So we are on the same boat :-( I will continue working on this testbed, if I encounter something interresting I let you know. Please tell us if you learn something relevant. - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
