Just installed htop and to my surprise it shows only 2 cpus. In sysfs I find quite a few references to cpu0..cpu7 so they're all there, no clue why htop doesn't find them. Well in /sys/firmware/devicetree/base/cpus/cpu-map/ there's cluster0 and cluster1 with 4 cores each, so maybe htop only shows the clusters.

SailfishOS activates/deactivates cores on demand. htop does not seem to notice and only shows cores, that were active when it was started. You can check with lscpu which cores are online.

Interesting! Maybe this is due to the newer kernel providing better CPU scheduling and power management and we can expect the same on the X as well once its kernel is updated ?

Just have a look in the Jolla store. There is an App that is called AIDA64. This App is showing 8 CPUs on my XA2 Plus. One thing I mentioned was that none of the cores went to sleep with no Apps open and no Sim card installed.
