[Oisf-users] CPU Affinity

[Lee Walker]

Hello
 
I've been reading up on CPU affinity settings for Suricata. I have my system configured correctly (I think). Would it be possible for someone to suggest what they would configure with the following spec server? HP DL380 Gen 9 fitted with 256G RAM Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                40
On-line CPU(s) list:   0-39
Thread(s) per core:    2
Core(s) per socket:    10
Socket(s):             2
NUMA node(s):          2
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 63
Model name:            Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz
Stepping:              2
CPU MHz:               1430.000
BogoMIPS:              4600.51
Virtualization:        VT-x
L1d cache:             32K
L1i cache:             32K
L2 cache:              256K
L3 cache:              25600K
NUMA node0 CPU(s):     0-9,20-29
NUMA node1 CPU(s):     10-19,30-39  The Intel NIC I'm using is using NUMA node 1 according to /sys/class/net/ens5f0/device/numa_node I'm running Centos 7.1 Any suggestions would be appreciated. The following is what I currently have in the yaml file  cpu-affinity:
   - management-cpu-set:
       cpu: [ 0 ]  # include only these cpus in affinity settings
   - receive-cpu-set:
       cpu: [ 0 ]  # include only these cpus in affinity settings
   - decode-cpu-set:
       cpu: [ "3-19" ]
       mode: "balanced"
   - stream-cpu-set:
       cpu: [ "3-19" ]
   - detect-cpu-set:
       cpu: [ "3-19" ]
       mode: "exclusive" # run detect threads in these cpus   
 
 
Regards
Lee
