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 profiled counters. From PI Profiler version 2.2.1. onwards, CPU +speed data is included when "Instructions executed" profiled. For files created +with earlier PI Profiler versions, 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 always 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.
+ +When the CPU speed data is included in the imported Profiler data file, a +CPU clock rate counter and graph are also displayed in the Performance Counters View.
