Created attachment 295855 wult graph c1e for stock and mwait modifed kernels - version 2
As Artum advised, with locked CPU frequencies.
Other data (kernel 5.12-rc2):
Phoronix dbench 1.0.2 0 client count 1:
stock: 264.8 MB/S stock, idle state 2 disabled: 311.3 MB/S (+18%) stock, HWP boost: 417.9 MB/S (+58%) stock, idle state 2 disabled & HWP boost: 434.3 MB/S (+64%) stock, performance governor: 420 MB/S (+59%) stock, performance governor & is2 disabled: 435MB/S (+64%)
inverse impulse response, 847 uSec gap: stock: 2302 tests 38 fails, 98.35% pass rate. + MWAIT change: 1072 tests, 0 fails, 100% pass rate.
@Srinivas: The whole point of the quick test stuff is that it self adjusts to the system under test.
