1. A method for improving performance measurement comprising: monitoring an application using a hardware performance measurement counter, the monitoring the application comprising identifying a plurality of events while the application is executing; analyzing the plurality of events in a multiplexing counting mode, the multiplexing counting mode using a hardware performance measurement counter to perform the analyzing; configuring a sampling time to more effectively perform sampling, the configuring the sampling time comprising identifying a group of operations for sampling and generating an interval sample time for the group of operations for sampling based upon the analyzing; and, determining how the plurality of events impact performance of the application based upon the monitoring, analyzing and configuring.
