File transfer application

Hi,
I want to test the performance of (Client-server application) file transfer application, where client will took a file from server and process it and once again client will transfer the file to the server in a desired location.

can we do testing this with load runner tool. yes, means which protocol can we use.

Thanks in advance.

Hi, This Client server application uses its own protocol called DO protocol (Data optimizer).

If any other tool other than Load runner is possible?.
