MIPS counter and graph

The Million Instructions Per Second (MIPS) graph gives you a general idea of -CPU speed in a measured use case. The basic use case for the MIPS analysis -would be to check any low areas in the graph since they may reveal unoptimized -features, for example, in terms of memory access (reads and writes). The higher -the MIPS values, the better and the faster the CPU is in executing -instructions.

A MIPS (Million Instructions Per Millisecond) graph is displayed in the -Performance Counters view, when Instructions executed has been selected -as one of the counters. If Instructions executed has been selected, the -dialog below is displayed during PIAnalyser file import:

- -

The processor speed information is needed for calculating the data for the -MIPS graph. The rest of the data for the calculation is included in the -Instructions executed and CPU cycles counters.

- -

The MIPS counter information is displayed in the graphs view and the legend -table together with the other performance counters. Note, however, that for -MIPS only Average (1/ms), Min (1/ms), and Max (1/ms) -information is displayed in the legend table.
