7206 VXR NPE-G1 throughput

    I have one but I never ran that much BW thru mine.

    But the CPU usage is what will kill you.

    Also the entire platform is rate for 1.8Gbs aggregated which mean
depending on which interface you have, and which bus they are connected
to, 900Mbps might be its limit.
