We're experiencing a performance problem with our 7200/NPE-G1 router. When doing an FTP session across the router, we noticed that performance was only 30-50 Mbit. When the test hosts are on the same network, performance is the full 100 Mbit the hosts are connected with. We also tried connecting the test hosts directly to the router interfaces, one interface for eac host, in a plain vanilla configuration. Performance was the same. When using simple bandwidth testtools like NetCPS the results are similar.
When testing in the same way over a 6500/MSFC2 performance was line speed, as expected.
MRTG monitoring seems to indicate that aggregate performance is higher than this, but we've been unable to get a single end to end test to go higher than 50 Mbps.
The router is configured to use CEF, and as far as we can tell, CEF is working properly.
Does anyone know what could be causing this? I would expect the NPE-G1 to be capable of handing 100 Mbps...
Below the configuration as we use it. G0/1 and g0/2 were used only for end-to-end testing, the .1q test used vlans 202 and 203 on g0/3
