The goal of this chapter is not to do benchmark to compare differents platforms, but to measure some metrics to be able to detect a performance regression after an update.
The most interesting metrics to measure are CPU computation, memory and cache performances, and the most important for a router, the network performances.
The tools iperf3 and stress-ng were selected to make these measurements. These tools are pre-installed in the demo profiles.
The stress-ng tool includes lots of tests, and in particular some network tests. The following tests were selected.
It's not an exhaustive list, and you are free to run other tests.
| Tests | Description |
|---|---|
| cpu | exercise the CPUs using different CPU stress methods |
| matrix | perform various matrix operations on floating point values (good way to exercise CPU fp operations, memory and cache) |
| fp | perform floating point math ops |
| crypt | perform password encryption |
| goto | perform forward/backward branches (exercises branch prediction logic) |
| bigheap | grow the heap by reallocating memory |
| malloc | perform memory allocations (malloc, calloc, realloc, free...) |
| memcpy | perform memory copies |
| bsearch | perform binary search (exercise random access of memory and processor cache) |
| hsearch | perform hashtable searching (exercise memory access and processor cache) |
| msg | send and receive messages using System V message IPC |
| getrandom | get random bytes from the /dev/urandom pool using getrandom |
| hrtimers | exercise high resolution times at a high frequency |
| daemon | put pressure on init (procd) to do rapid child reaping |
| fork | perform forks |
| netdev | exercise various netdevice ioctl commands across all the available network devices |
| rawpkt | send and receive ethernet packets using raw packets on the localhost via lo device |
| rawsock | send and receive packet data using raw sockets on the localhost |
| rawudp | send and receive UDP packets using raw sockets on the localhost |
| sock | perform various socket stress activity |
| sockfd | pass file descriptors over a UNIX domain socket using the CMSG ancillary data mechanism |
| sockmany | open as many as 100000 TCP/IP socket connections to a server |
| udp | perform udp transfers |
To get more details about these tests, please refer to the stress-ng project
The command used to run these tests is:

metric (to compare with previous sessions) is the bogo ops/s (usr+sys time).
Note that bogo op depends on the stressor being run, and are not comparable
between different stressors.

Iperf3 is a network bandwidth measurement tool that support UDP and TCP network protocols. It will be used to measure the bandwidth of all network interfaces (to detect performance regression), and validate that the hardware is functional.
For the wifi tests, they are only run in access point mode.
Iperf3 tests will also be run on the loopback interface. These tests are used to stress as much as possible cpu, memory, cache and network stack. The values can be used to detect a performance regression, but they don't correspond to a reachable bandwidth. The bandwidth of the board will be limited by the hardware interfaces.
Note that wifi tests are very sensitive to the test environment (hardware used as wifi client, distance between client and access point, other wireless networks, ...).
Some of the bandwidths may not be optimal, they can be improved with very fine tuning. But it's not the goal of this part. The goal is to do basic tests with the default configuration (which can be reproduced easily), to validate the hardware and detect performance regression for the default setup.
