Dave,
We can test and compare apple with oranges in that
respect. Why?. GSR internal architecture is based on
shared bus/cpu while GSR using distributed, cross-bar
architecture. Therefore, to perform the test fairly
you should load the M-xx with PIC's and the GSR with
8, 12, or 16 lincards and verify the performance.
Also, could you please clarify what type of GSR LC
that you test against?. Cisco has 3 generation of line
cards, their OC48/QOC12-POS is able to forward raw
data throughput up to 4 Mpps, which I don't think
Juniper can accomplish that with fully populated box.
