10.4.3. About Concurrency Levels

Concurrency refers to the number of threads simultaneously interacting with the data grid. In Red Hat JBoss Data Grid, concurrency levels refer to the number of concurrent threads used within a lock container.

In JBoss Data Grid, concurrency levels determine the size of each striped lock container. Additionally, concurrency levels tune all related JDK ConcurrentHashMap based collections, such as those internal to DataContainers.
