Next round of tests, this time with a cheap heatsink (low price, low profile, low performance -- do a web search for 'cubie 20x20 heatsink'): http://openbenchmarking.org/result/16031...603107GA53
Comparing the last 2 results shows that just the heatsink is responsible for ~20% or even more performance with multithreaded workloads in the same situation (no airflow possible, Pine64+ in a small enclosure). But more importantly no CPU cores were killed and CPU clockspeed was adjusted to 816MHz instead of 600MHz as before:
Next step is to activate missing clockspeeds, currently longsleep's settings contain only the following:
And now I'll try it with a few more:
