Some data to take into consideration. I've tested 4 difference configs (3 laptops, 1 server) of mixed Intel and AMD hardware, comparing the default powersave/ondemand [1] vs performance
[1] depends on CPU and if intel-pstate is supported
For faster modern Intel CPUs where intel-pstate is supported, there is minimal difference. Otherwise, performance is a ~3% faster, and all the gains are in userspace.
See attached spreadsheet.
Tests data was gathered from the average of 25 and average of 50 boots per CPU scheduler setting. So that's a total of 600 boots in this dataset across a range of H/W, so I think this data is pretty reliable data.
