Hi Laurent,

I downloaded your script and run it on Intel 2s skylake platform with spf-v12 patch
serials.

Here attached the output results of this script.

The following comparison result is statistics from the script outputs.

a). Enable THP
                                            SPF_0          change       SPF_1
will-it-scale.page_fault2.per_thread_ops    2664190.8      -11.7%       2353637.6      
will-it-scale.page_fault3.per_thread_ops    4480027.2      -14.7%       3819331.9     


b). Disable THP
                                            SPF_0           change      SPF_1
will-it-scale.page_fault2.per_thread_ops    2653260.7       -10%        2385165.8
will-it-scale.page_fault3.per_thread_ops    4436330.1       -12.4%      3886734.2
