I observe strange think even now. On intel cpu WU was crunching in 10 second, and the same WU on ODROID-XU4 on arm was crunched in 45minutes.... maybe it's because ARM does'n support hardware random. What do you thin about it?

I know that ARM is weak instead of intel but this is terrible BIGtime diffrent.

ps.: Even on DrugDiscovery@Home I don't have that kind of diffrent time against intel/amd.
In that case there is no sense to crunching monkeys cpu on arm... ?

If you compare intel with linux and arm with linux, it is not so different.
Intel with Win is much faster than intel with linux.

Not in everythink.
I tested cpu app on win 64bits and lin 64bit, diffrent in processing time was about 5-7sec. Win 64b need 10-12sec on my i7, and lin 64bit on my i7 need 15-19sec <- it's not much... but this differences will be BIGGER when I start generating WU for about 1-1,5h work.


ps.: I try to install some strand library on my odroid-xu4 and recompiling kernel, but without any success. I am a little confused about it <- or I in big shock... that this arm's cpu don't like random operation.
At this moment I have to make some tests with my neural network which I were planning to place on 25x Odroid-XU4 <- if my 4-5x XU4 will be so slow even with machine learning I will have to re-plan NN.
