Dear All

I took the following note from cisco site

Wire-speed performance on 3825 with services enabled at up to T3/E3 rates.

my quiestion is.

does this apply if i use Cisco Gigabit Ethernet Network Module to connect it to my service provider, in other words, can i get 1 GIGA throuput out of the router despite the upper statement using the GIG NM or using the SFP placed on the router.

The 3825 has a Switching capacity of 179 Mbps or 350,000 pps under ideal conditions.

I think you can safely load the router till the above value

Have a look at the attached document

HTH, rate if it does

If it is rated for wire speed up to T3 (45 meg) then I would not count on getting wire speed using a Gig interface. The performance of the router is somewhat dependent on what you are asking it to do (how many services you enable on it) but I would not expect to get wire speed performance on the Gig interface.
