Tests of routerboards

Hi,
I plan to do some comparative throughput tests with several routerboards, so, normis, can you please tell me which tests do you do when you measure capability (performance) of routerboards?

I am interested in wireless/lan speed with nstreme and multiple wifi links. My network is heavy loaded practicly all the time, so, I need routerboard with 3-4 minipci cards, and full speed (30-50Mbit/s), all at same time. (I am targeting at RB600, but, somehow, I have feeling it will not have enough cpu for 3-4 nstreme links)

I hope I would be able to get this goal.

Any recommendation will be great…

I had in plan to take several boards, and do speed compare between them, than with PC as router on other side (with mikrotik), and as final, with alix board.

Thank you
