Thanks - I have been monitoring the Raspberry Pi's current frequency by looking at: /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq Even after adding force_turbo=1 to config.txt and rebooting, cpu0 never seems to scale above 600 A closer peek at $ sudo cat /sys/devices/system/cpu/cpufreq/policy0/* shows that some of the cores will occasionally hit 900, 1200, 1400MHz so you're correct that the CPU frequency support in the kernel is working. It seems that Gnome Shell / wayland drags down performance on the Raspberry Pi so much that opening Firefox takes 10 minutes. I'd prefer to run Gnome but its unbearable. I've done a $ sudo dnf groupinstall lxde-desktop-environment and LXDE performance is much better. -- John _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/arm@xxxxxxxxxxxxxxxxxxxxxxx
