One place to examine application performance is in the message processing part of the application. To help you gather this performance information in BlazeDS, you can enable the gathering of message timing and sizing data.
When enabled, information regarding message size, server processing time, and network travel time is available to the client that pushed a message to the server, to a client that received a pushed message from the server, or to a client that received an acknowledge message from the server in response a pushed message. A subset of this information is also available for access on the server.
