Synchronization Objects (SAP DB) 
This provides you with an overview of access to the exclusive main memory structures (synchronization objects or regions), including information about which process (task) accessed the main memory structure.
These statistics are useful for analyzing the cache activity or any resource conflicts. Conflicts occur when several requests are sent to one resource simultaneously. If the number of conflicts is more than 10% of the total accesses, this indicates severe bottlenecks in your system.
