Hi Luca and Alfredo, Keep up the great work. Just wanted to let you know some numbers with r6405.
I have been testing between two systems that have a 10 gigabit fiber connection. I have been using netperf to send tcp data from server A to server B, one stream only. Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz 4GB memory CentOS 6.x 2.6.32-358.6.1.el6.centos.plus.i686 I have been able to capture with stock libpcap 8.8 to 8.9 Gbps ~ 100,000pps with minimal packet loss < .03%. CPU for ntopng at about 44% of one core. With pf_ring in mode 0 - no packet loss and CPU for ntopng is about 4% $ cat /proc/net/pf_ring/info PF_RING Version : 5.6.1 ($Revision: 6405$) Total rings : 0 Standard (non DNA) Options Ring slots : 4096 Slot version : 15 Capture TX : Yes [RX+TX] IP Defragment : No Socket Mode : Standard Transparent mode : Yes [mode 0] Total plugins : 0 Cluster Fragment Queue : 0 Cluster Fragment Discard : 0 -- Stephen Clark *NetWolves* Director of Technology Phone: 813-579-3200 Fax: 813-882-0209 Email: [email protected] http://www.netwolves.com
