Without the patches applied With the patches applied
31.8s 30.4s
------------------------------------------------------------------------------ ------------------------------------------------------------------------------
Kernbench make -j8 results on a 8 core x86 machine _without_deep_sleep_ support (only mwait)
Without the patches applied With the patches applied
20.2s 20.4s
------------------------------------------------------------------------------ ------------------------------------------------------------------------------
Kernbench make -j8 results on a 8 core _dedicated_lpar_pSeries_ machine
