Embedded x86 Benchmarks

[Lonnie Abelbeck]

Greetings,

I have a collection of lower-end (embedded) x86 boxes that I use for testing with our AstLinux project.

I ran iperf3 tests of WireGuard performance with a common "fast" VMware VM WireGuard endpoint.

Interestingly the J1900 and N2930 can saturate the 1 Gb interface with 1 to 1.5 CPU cores still available.  The similar OpenVPN performance maxes out at only 100 to 130 Mbps of tunneled traffic.

Also note that the Lanner Atom N2800 system is 32-bit (i686), so even with 'ssse3' it appears there is no optimization, and the performance reflects that.

Hopefully others find this interesting.
