Sun GlassFish Enterprise Server 2.1 Performance Tuning Guide


With web-method persistence frequency, the server writes the HTTP session state to HADB before it responds to each client request. This can have an impact on response time that depends on the size of the data being persisted. Use this mode of persistence frequency for applications where availability is critical and some performance degradation is acceptable.

For more information on web-method persistence frequency, see Configuring Availability for the Web Container in Sun GlassFish Enterprise Server 2.1 High Availability Administration Guide.
