Summary of Actual Replication Test Results

Replication tests were run using up to four instances of the OpenSSO Enterprise embedded configuration data store with Tomcat and GlassFish. The results show that replication was successful among the four instances using 8000 policies. The following is a summary of the test results:

• When all four instances are online, the delay of synchronization of replication is generally less than one second, which is negligible.

• The time required to load the same amount of data in an embedded configuration data store instance is longer when replication is enabled whether or not all instances are online.

• The time required to load the data is incremental. The time required to load the second 1000 entries is longer that the time required to load the first 1000 entries.

• Data loading time can be significantly reduced by breaking up the data and loading data at the same time using multiple instances.

• With the same amount of memory heap size (2GB), Tomcat performs better than GlassFish v2 for smaller settings (one or two instances). GlassFish performs better in larger settings (four instances).
