A method is provided to establish affinity for each pair of processors with a specific processor bus which eliminates the need for cross-bus operations in cache invalidation operations. Each pair of processors in the network is exercised for elapsed time of cache update cycle completion. Those pairs having the minimal execution times are then selected for utilization of applications to be executed.

Affinity checking process for multiple processor, multiple bus optimization of throughput

Parametric data accumulation means are accumulated in a Terminal Server data file which uses a performance measurement tool program to accumulate operational data occurring in multiple client users which operate on a Terminal Server. Data is accumulated in regard to the log-on time for multiple and various different types of application programs. Each of these parameters are evaluated over a sequence of different operating conditions during periods where the parametric evaluations occur when there is a small number of client users and then over a sequence of expanded operations until there is a large number of concurrent active client users. Subsequently, the Terminal Server data file is formatted and categorized into a database which is used to create a graphical chart of performance plus specific lists of performance for each client-user correlated to each available Application Program.

Terminal server data file extraction and analysis application

A performance measurement tool is developed to measure performance of a terminal server servicing multiple Clients who operate on remote systems in a farm of multiple PC's. Test scripts to simulate actual operating conditions are run on each PC Client-User over a sequence of time which varies the number of concurrently active PC Client-Users from a small number of Users to a vary large number of current Users. During this test period, a record is kept of designated simulated-user-initiated actions such as log-on times, time to open various application programs, and character entries thus to determine acceptable operating configurations.
