build options on Raspberry Pi 2 (model B)

[cryptozeny]

i don't think that it's not actually issue, but I wanna share this.

i used this options on rpi2.

$./configure CFLAGS="-Ofast -mcpu=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -ffast-math" CXXFLAGS="-Ofast -mcpu=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -ffast-math"

and i got 25% hash up. it's amazing... before 0.08 kH/s after 0.11 kH/s

do you why this options increases hash power? i am very curious...

the options from this site:

i think it's very practical for ARM CPUs (smartphone mining)

I guess due to neon and -Ofast
