A method for measuring performance of test points having one or more instructions in a code sequence. A code sequence with two or more test points is repetitively executed, while measuring the execution time. The code sequence is modified by removing one test point. The modified code sequence is repetitively executed, again measuring the execution time. The modification and execution steps are repeated until no test points remain in the current code sequence. All execution and modification steps are repeated a defined number of times, saving the execution times to a data file. The minimum execution time for each code sequence from any run is assigned to that code sequence. The execution time of a particular test point is calculated by subtracting the assigned execution time for the code sequence after removing the particular test point from the assigned execution time for the code sequence be fore removing the particular test point.

Method for measuring performance of code sequences in a production system

Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).
