In the past few days, I have puzzled by NFQUEUE in bridge mode.
I have take some test with five kernels.
2.6.24.4
2.6.36.4
2.6.38
3.0.8
3.1.10
The result is : 2.6.24.4,2.6.26.4,2.6.38 have a goog performance;
3.0.8 and 3.1.10 have a poor performance.
Next is copy from suricata maillist( eric@regit.org )
I'm having a look at it. There has been some changes between the two
kernel versions (bringing more performances) but it seems there is some
side effects with bridge.
Thanks!

More data is welcomed. What is "good", what is "bad" ?
You dont expect us to magically understand the issue, do you ?
If you want some help, you should give as much information as possible.

Sorry for that.
My network is 100Mbps.
"good" means the forward bandwidth almost 100Mbps.
"bad" means the forward bandwidth with nfqueue only 30Mbps.
Thanks for your reply!

more info needed... like what kind of network adapter do you use , and
ethtool -k settings, like
ethtool -k eth0

Might be the 'gro+nfqueue eats MAC header' problem, you could try
commit a8db7b2d197a0d624baab83f0c810b0edbc4ffd0 (netfilter: nf_queue: fix
queueing of bridged gro skbs). Or, disable gro on all bridge ports via
ethtool -K $device gro off
If its not gro related, please provide more information about your
machine, setup, ... etc.

I have test it.You are right.Now it is time to learn why the gro effects it.
Thanks very much.
