Thanks guys for valuable inputs...last question...will terminating gig
link at 3560 or 6509 solve my purpose and give 1Gbps?

The bottom line is if you want the ability to route 1gbps, you are in
the
wrong line.

Thanks Paul. Please let me know your test result tomorrow.
Please note I am not doing any encryption on this router.

Have just tested a 3835 with a copper g0/0 and a fibre NM-1GE. Using
just a traffic generator and the router I'm seeing up to:-
405 Mbps with 1518 byte frames.
323 Mbps with 200 byte frames.
282 Mbps with 82 byte frames
The cisco stats have the router rated at a little less than this,
256Mbps @ 64 byte packets:

terperformance.pdf
The router supports an MTU of 9000, but the equipment I have seems
reluctant to generate jumbo frames (may not be supported). This router
just has a basic config, bgp and sub interfaces. Features which change
the forwarding path are likely to reduce throughput. If I have time
tomorrow I'll try the two onboard NICs and let you know if there is any
difference.
With encryption, pps tends to be much more important than bps. Even
high end encryption devices can show surprisingly poor performance when
pushing small packets.

Depends on your packet sizes.
With ideal condition, I've seen 500Mbps.

Hi Guys,
Can any one please confirm that cisco 3845-MB router with onboard
Gigabit interface (RJ45 or SFP) supports how much of maximum throughput?
Does it has maximum throughput of 256Mbps only?
Thanks
Subodh
