Thanks a lot Ian and Gary for your answers. You give me useful information which could help me.

I will try 1000MT cards to see if performance is improved.

Thanks,

Jorge

We have a testing environment, with a Intel(R) Pentium(R) D CPU 3.00GHz, 1 GB memory, a Realtek RTL-8169 NIC, where we want to reproduce the improvement of PF_RING functionality. It also has a separated NIC for administration. There is a Debian etch 32bits running. We will use tcpreplay for injecting traffic (using a real capture from the real environment)

In our testing environment, following the howtos about PF_RING, we have downloaded the code, edited and run mkpatch... We have a comment here... this script does the patch itself?? You don't need to execute "patch" afterwards as the instructions say. Just a point.

We execute make menuconfig and select the options (rx and tx polling for r8169 as a module, PF_RING sockets as a module) and generate the new kernel which we boot (Debian like). No problem


I once tried to capture traffic with an r8169. I gave up very quickly, and fitted a Pro-1000 card. I think at first I jammed a server card in the 32-bit slot in the machine I had, and it worked, until a few 1000-MT desktop cards arrived. It made a huge difference on the test hardware we had.

I'm successfully capturing 5 minute averages in excess of 500Mb @~ 80kpps on a PE1850, in 32 bit mode, on an 82541 Intel GE, using ring 3.7.7.

# cat /proc/net/pf_ring/info
Version             : 3.7.7
Bucket length       : 1514 bytes
Ring slots          : 8192
Slot version        : 9
Capture TX          : No [RX only]
IP Defragment       : No
Transparent mode    : No
Total rings         : 2
Total plugins       : 0
