Ah, now I get it. The Docker file still references Ubuntu 17.04. A simple change like this https://github.com/bamarni/pi64/pull/65 should be sufficient. No idea why @bamarni didn't merge the PR but...

With most recent kernel (hoping for @bamarni to provide a new release soon) we can now check for this problem on our own and without using `vcgencmd get_throttled`. All that's...

@503612068 unfortunately you can't check for 'frequency capping' asking the kernel since `/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq` contains only fake values in situations where either frequency capping or throttling occurs. So you need to...

You can also run in another terminal the following in parallel to get an idea about the real clockspeeds of the ARM cores: while true ; do vcgencmd measure_clock arm...

Well, the `sysbench` 'test' is the most unreliable one (since sysbench is such a light load). But I don't know whether `vcgencmd` is now available in pi64 or not. In...

BTW: Good news. With most recent kernel and 'firmware' Raspberry Pi problem N° 1 (under-voltage due to encouraging users to use crappy chargers and crappy 'power cables') has been somewhat...
