[ Including the thread from osif-users for context ]
I'm testing out suricata and pfring. Currently, I'm running suri
using 22 pinned threads on the default 10G/82599ES interface (enp4s0),
and it's working fairly well.
Suricata config :
- interface: enp4s0 # Number of receive threads (>1 will enable
experimental flow pinned
# runmode)
threads: 22
I tried using 22 ZC queues, configuring suri like this:
- interface: zc:99@0
threads: 1
- interface: zc:99@1
threads: 1
[...]
- interface: zc:99@21
threads: 1
and zbalance like so:
./zbalance_ipc -i zc:enp4s0 -m 4 -n 22,1 -c 99 -g 0 -S 1
and it seemed to work, however, the performance was drastically reduced.
With normal pf_ring (-i enp4s0) :
capture.kernel_packets | Total |
13211759633
capture.kernel_drops | Total |
3867805
With 22 zc queues:
capture.kernel_packets | Total |
92423279
capture.kernel_drops | Total |
619667008
I also tried just using one ZC queue, but found I seem to get better performance
with the multi-threaded non-ZC version.
Is there something I can do to get the benefits of both ZC and multi-threading?
Thanks,

Leaving off the -i seems work, thanks for your help.
Unfortunately, performance drops significantly with this setup.
With normal pf_ring (-i enp4s0) :
capture.kernel_packets | Total |
13211759633
capture.kernel_drops | Total |
3867805
With 22 zc queues:
capture.kernel_packets | Total |
92423279
capture.kernel_drops | Total |
619667008
I guess this is a question for the pfring list.
