Glassfish, big network traffic

[hoseka]

Glassfish 3.1.2.2 transport protocol when working with statefull, sends a lot of data over the network.
Application needs a few kilobytes (records is not much), and Glassfish transmitting on the network 20 MB. Because of this, customers with a slow Internet connection (less than 2 Mbit / s) will experience discomfort when using the application.
If I deploy the application in jboss, then everything works fine.
Perhaps Glassfish communicates what that inside information with the application, slowing its work.
On a network some thousand almost identical packages (look screenshot) are transferred
Can I disable this?
