96 There can be multiple performance profiles on a system. To get the number of
111 On this system under test, there are 4 performance profiles in addition to the
112 base performance profile (which is performance level 0).
117 Even if there are multiple performance profiles, it is possible that they

261 Which shows that the base frequency now increased from 2600 MHz at performance
262 level 0 to 2800 MHz at performance level 4. As a result, any workload, which can
263 use fewer CPUs, can see a boost of 200 MHz compared to performance level 0.

309 This means that at performance level 4, the "speed-select-base-freq" feature is

547 Performance Profile (Intel(R) SST-PP) performance level configuration. It is
548 possible that only certain performance levels support Intel(R) SST-BF. It is also
549 possible that only base performance level (level = 0) has support of Intel
550 SST-BF. Consequently, first select the desired performance level to enable this
554 performance level 0, but currently disabled. For example for the level 0::
569 performance, execute some workload and measure performance and get a baseline
