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
Thanks,
Haiyan Song
