RouterBoard process in 100%

Is a routerboard good enought to process a lot of data, because when I run btest and sometimes a don’t get enought traffic and the processing of cpu is in 100%, a pc x86 with 2 GHz is better for processing data or it will be the same.

Sure, the reason it runs up to 100% running a btest is because the router has to create all of the traffic it is sending out. It is better to test through your routers and not from them.
