Top Most How to improve RMI performance

Can I use compression to improve RMI performance when transferring large datasets between the client and server?

Answer 

Yes, you should be able to use the ZipInputStream and ZipOutputStream classes within a custom socket factory to give you a new socket type that transparently compresses data.

When you construct your ServerImpl, don't use the constructor that takes the port number, use the default constructor.

so use

      ServerImpl server = new ServerImpl();

      Registry r = LocateRegistry.createRegistry(1090);

      Naming.rebind("//localhost:1090/ZipServer",server);

NOT

      ServerImpl server = new ServerImpl(SOME_PORT);

      Registry r = LocateRegistry.createRegistry(1090);

      Naming.rebind("//localhost:1090/ZipServer",server);
