We have a network provider that has linked our 3 offices with LANlink. Office A (cisco 4503) is connected to the provider with 1 Gbits fiber optic full duplex Office B (cisco 3750) is connected to the provider with 100 Mbits full duplex Office C (cisco 3750) is connected to the provider with 10 Mbits full duplex
These lines are still on test so they are not in production yet. When I try to do ftp between office A and office B, I got 1 Mbyte/s. Normally I should get around 10 Mbytes/s. I complained to the provider, the technician told to use NetIO command line software. This software do test with packet of 1K, 2 K, 4K, 16K and 32K. So I put on one end the tool on listening mode and on the other end it send the data. Indeed the testing gave a throughput of 10 Mbytes/s (100 Mbits line).
I was not convinced as the packet are too small, I used then another command line software NetCPS. This tool work in the same manner but it send a file of 100 Mbytes. Here the troughput was the same as the ftp: 1 Mbyte/s. It took 73 seconds to send 100 Mbyte file.
The Cisco switches are new and we just use static routes. We do not have any QoS.
I would appreciate if you can give some help on this
