摘要： 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.

摘要： A method and system for using multiple versions of a software component, includes storing, in memory, a first function table that points to executable code in the memory for functions from a first version of the software component, and storing, in the memory, a second function table that points to executable code in the memory for functions from a second version of the software component, referencing the first function table, when running a first application thread, to execute the functions from the first version of the software component; and referencing the second function table, when running a second application thread that is active concurrently with the first application thread, to execute the functions from the second version of the software component.

摘要： 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.

摘要： A method and an apparatus to locate a bottleneck of a Java program. The method to locate a bottleneck of a Java program includes the steps of: creating a helper thread in a Java process corresponding to the Java program, and attaching the helper thread to a Java virtual machine (JVM) created in the Java process; inserting a prober into an operating system kernel; monitoring states in the operating system kernel of Java threads in the Java process and sending a signal to the helper thread in response to detect that a Java thread is blocked; and retrieving call stack information from the JVM in response to receive the signal from the operating system kernel and locating the position in source code of the Java program that causes the block using the retrieved call stack information.
