hi all
MG
When data traffic comes in at about 2.5Gbps, one of my cores gets overwhelmed. Has anyone ever experienced this? I'm using an Intel X520.
MG
one moment
MG
At this moment the traffic is low and so it is normal.

This is a Dell R420 with dual Intel(R) Xeon(R) CPU E5-2420 v2 @ 2.20GHz
MG
With 4000 subscribers
MG
Yes, in the absence of IPv4 blocks I pass to subscribers 172.21.x.x
MG
Can be NAT?
DF
if it is newest kernels(where nat has special process to cleanup conntrack) and you have some sort of unidirectional flood from one of users - it might happen
DF
in your case i see on CPU6 asymmetry, pppoe?
MG

yep
DF
most probably then just issue of X520, they can't load balance pppoe
you need to check, maybe you have too many rules in firewall or conntrack has too many connections

try to check this value:
sysctl net.netfilter.nf_conntrack_count
sysctl net.netfilter.nf_conntrack_count
MG
net.netfilter.nf_conntrack_count = 78338
DF
at the moment it is very low
