 Set the parallelism of concurrent execution for subscribers by specifying the value of the `GroupConcurrent` parameter. Concurrent execution means that it needs to be on an independent thread, so if you do not specify the `Group` parameter, CAP will automatically create a Group using the value of `Name`.
 
 !!! Note
-    If you have multiple subscribers configured with the same Group and have also set the `GroupConcurrent` value for them, only the first configured value will take effect.  
+    If you have multiple subscribers configured with the same Group and have also set the `GroupConcurrent` value for them, Then the degree of parallelism is the sum of the values in the group.  
     This setting applies only to new messages; retried messages are not subject to the concurrency limit.
