FD.io performance report (detailed - official baseline)

our architecture: 10ge2p1x520-eth-l2xcbase

The full list can be found here. The current list is actually sufficient for our experiments.

1. Check NUMA nodes matching: CPU -> NUMA node <- Line card

• To check CPU: lscpu | grep NUMA
• To check LINE CARD: cat /sys/class/pci_bus/$PCI_PREFIX/device/numa_node
• Graphical tool: lstopo

Sample output:

lscpu | grep NUMA
 NUMA node(s):          2
 NUMA node0 CPU(s):     0-11,24-35
 NUMA node1 CPU(s):     12-23,36-47

cat /sys/class/pci_bus/0000:84/device/numa_nodes
 1

2. Set CPU in performance mode

• Warning: This activates turbo boost. Remember to change

sudo cpupower frequency-set -g performance

3. Deactivate turbo boost

echo 1 | sudo tee  /sys/devices/system/cpu/intel_pstate/no_turbo

to check frequency:

sudo cat /sys/devices/system/cpu/cpu${id}/cpufreq/cpuinfo_cur_freq
