Lock waits/second is creeping upward - 15 to 20 is not uncommon. Is this something which should concerning? What can be done to lower lock waits/sec? Thank you!
7. SQLServer: Locks: Lock Waits / Sec: _Total
In order for SQL Server to manage concurrent users on the system, SQL Server needs to lock resources from time to time. The lock waits per second counter tracks the number of times per second that SQL Server is not able to retain a lock right away for a resource. Ideally you don't want any request to wait for a lock. Therefore you want to keep this counter at zero, or close to zero at all times.
