Re: apt-build optimisation

-mfpu=neon-fp-armv8 is (slightly) better for the Pi3, though it probably wont help with sysbench. I will change it :) Thanks! This benchmark is a bit limited because the performance is dominated by the division/remainder operation. All arithmetic in the benchmark is 64-bit. Both CPU's are 32-bit or...

Re: Pi 3 power consumption / undervolting

I... Negative values... I didn't know you could do that. :lol: have a look at http://elinux.org/RPiconfig I am at the opposite end of you. I want stability so I only use positives, lol. Why do you use more power to get a stable system? I believe you'll get a more unstable system cause of overheatin...

Pi 3 power consumption / undervolting

Hi, got my Pi 3 yesterday and i am really happy. (I used my Pi 1 for more then 2 years now and it works real good, but 2 nextcloud users... horror) This is my actual config.txt at Pi 3: arm_freq=1200 arm_freq_min=150 core_freq_min=250 sdram_freq_min=250 over_voltage=-3 over_voltage_min=-8 #over_volt...
