241 To the change the performance level to 4, execute::
243 # intel-speed-select -d perf-profile set-config-level -l 4 -o
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.
