A method and apparatus for a native method call. The method comprises: generating, in response to a native method call-associated event, a template copy from a generic template for processing the native method call; filling information required for processing the native method call in corresponding locations in the template copy; and changing a code execution flow to execute the template copy. When a native method is called, the native method is processed by dynamically inserting the template copy in the execution path at the assembly level.

A requesting critical wait time of a given resource may be determined. The requesting critical wait time is the time spent by the one or more resources waiting for the given resource, wherein at least one of the resources waiting for the given resource can proceed if access to the given resource is granted. A requested by critical wait time for a resource is determined, the requested by critical wait time being time spent by the resource for waiting solely for the given resource, wherein if the resource were granted access to the given resource, the resource can proceed without further waiting.
