Strange OpenSSL RSA speed Test issue

[_835_]

Hi guys,


i require your helps and ideas.

i run openssl speed rsa to evaluate the power of my PINE64+ board (i am a crypto guy).



i was a litle bit surprised to see big difference using different distribs :

 - the Debian Jessie with Mate DE [3.10.102 BSP 2] by Lenny Raposo    show me a nice 9.6 4096bits Private RSA / sec



while other dietPI and armbian get stuck to 6.4 4096bits Private RSA / sec.



So i decide to upgrade both the Debian Jessie Mate and dietPI to the latest kernel 3.10.105, run package update, then i force the CPU setting got from the debian to the dietPI :

sampling_down_factor = 1

sampling_rate = 2000000

sampling_rate_min=40000

up_threshold = 95



but got same result dietPI still show me  6.4 4096bits Private RSA / sec.

What do i miss ?


Any helps appreciate, thanks a lot
