Routerboard pps?

Does anyone know what the packet per second capability of a routerboard is? I’m interested in both the 200 and the new 500 series.

I would like also to know if any limit is documented.

Depends on the packet size.
Starting from 25K+ for small packets ending with 16K+ on large ones without conntrack for RB 532.

good. we use rb512 with atheros cm9 for radio links point to point.
is there any limitation (I mean maybe atheros wireless card dont support so many packets).?
