Slow routing on Cisco 7204vxr router

[dna86]

I have a Cisco 7200vxr router with an NPE-400 processor in it. I am setting up a network with two subnets and would like to use the 7200 to route between them. For a test, I have a 2950 switch and two laptop computers. I setup the switch with two VLANS to connect the computers to the router. Then, I am testing by copying large files from one machine to the other.

I started setting up a 2621XM router with two ethernet ports. When copying files, I get about 8-9MB per second throughput which is good utilization of fast ethernet.

Then, I moved the configuration to the 7200. My throughput dropped to about 450KB per second and I can't figure out why it's so slow. I checked the interfaces. Both are showing 100mb and full duplex. The CPU utilization on the 7200 runs around 1-5% so it's not overloaded.

Any clues about what to try or where to look?

I am running c7200-advipservicesk9-mz.150-1.M.bin as the IOS image.

Here is the status of the first interface:

As you can see the PPS is around 300 packets per second. I know something is wrong but can't seem to find it.

Maybe you can post the 2950 port configs along with the 7200 port configs .

Also, I have been working on this for 3 days now with no results. When I fired everything up this evening to respond to your reply, it is now running fast and fine. Go figure! I would still like to know what was happening. Also, are there monitoring and testing programs that can be used to troubleshoot network throughput problems? I have wireshark but that seems like more of a packet analysis program. It would be nice to have a packet generator that would flood packets for testing. Any pointers would be appreciated.
