Is there any way to enable these other cpus? My Ubuntu 16.04 installation
has them all enabled and the Ubuntu responsiveness is much quicker. I
suspect this has something to do with it.
So it's shut them off, it's something with the way the big.LITTLE
stuff works, so it's basically as expected. I believe it's handled as
part of the cpufreq policies from user space but I've done little with
the b.L stuff so I'm not sure. I'd try with the performance policy
first.
In terms of speed vs other distros, it would likely depend on a lot
more than just the cores that are running but I have no idea what
you're doing with it (remote server/desktop/what ever) so there's
likely a lot that will come into play.
