Abstract
A method of dynamic performance balancing in a distributed computer system including collecting average service time statistics for application requests distributed from multiple application servers and collecting application server CPU utilization statistics from multiple hosts where each host is associated with at least one of the application servers. In addition, the method includes periodically calculating scaled routing weights from the average service time and CPU utilization statistics and distributing server requests to the application servers in accordance with the scaled routing weights. Also provided is a distributed computer system configured to accomplish dynamic performance balancing as described above, and an article of manufacture for use in programming a distributed computer system containing instructions to accomplish dynamic performance balancing of server requests as described above.
