AIUI, Java WebStart is nothing but a delivery mechanism for an application to reach the client machine.  So another name for a "Java WebStart application" is a "Java application".  Look to your application for bad network habits.

Many network-separated applications manage the "Great Divide" between nodes very badly.  Common mistakes include doing to little with each crossing, causing communication overhead to dominate bandwidth; initiating a send from both ends to each other, instead of having one end be requester-only (the client) and the other responder-only (the server); and using file I/O as intermediate steps.

There are network factors beyond the program's control, of course.  The server connection just might be over a very thin pipe.

There's not enough information in your post for us to diagnose what your bottleneck is.  Run some diagnostics, such as a bandwidth test (or at least a ping) between the nodes involved.  If your bandwidth is only 256 Kbps between the nodes, nothing is going to go much faster over that link.  (You can play games with compression to increase the perceived bandwidth, but that comes at a cost of effort and complexity.)

Give us more data to work with, and look into what your application is doing with its bandwidth.
