Hi.
I tried to test RouterOS x86 (5.26) on an AMD 2650 (AM1) with ASRock AM1B on test tcp I noticed that uses a single CPU cpu0 100% cpu1 is 1%, and is limited to 560 MB / s If make routing works both cpu

With last version(6.34.1) goes much better, transfer speed reaching close to 1GB/s TCP and the CPU is at 70-80%

Never run the "Bandwidth test" on the system under test. It is not clever
You are testing the traffic generator performance.

Thank you for the advice. Basically works pretty well , I think it's more Powerful than the RB3011

Anyway in version 6.34.1 works much better.
