Responce time

[ekrogh]

Hi

I have an odd problem with responce time in a client server application.

If the client and the server is placed on the same vlan we have ok responce time, less than 20 seconds.

If the client and the server is placed on 2 different vlans the responce time varies

from 30 seconds to more than 1 minute. The switch hardware is the same, we just reconfigure the vlan setup.

I have checked the core routers - Catalyst 6509 switches with supervisor I modules

CPU utilization for five seconds: 11%/3%; one minute: 12%; five minutes: 12%

If I am pinging the server with 5000 bytes packages, I get this picture

Ping statistics for yyy.xxx.3.242:

Packets: Sent = 755, Received = 755, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 9ms, Maximum = 13ms, Average = 9ms

Control-C

I can copy a 24 mbyte files from the server to the PC and back in 3 - 5 seconds.

The server and the switch interface, it is connected to, has been checked and it is not the problem.

All this has been checked at the same time as the application is having problems.

The application programmer keeps saying the network is the problem, so I need some ideas about what to look at next !!

Thanks

Erik

Hello,

can you post the config of the RSM when different vlans are configured ?
