Hello
I updated F18 KDE to F19 MATE a few weeks ago. Been trough Beta to 'Test compose' (TC6 right now). I always do a clean install. With updates and tweaks the OS has been working very well, though one of the big concerns for me from day one was the very poor performance I was getting in CPU intensive applications. No matter how much I tweaked and investigated I wasn't getting a definite boost in performance, when in F18 i had no such issue (I was expecting the opposite actually).
Today I was checking the desktop panel and added the "CPU frequency Scaling Monitor" applet to it, and to my big surprise it showed each core at '1.6Ghz - Power Saving mode'... I started "Kerbal Space Program", a very CPU intensive indie game, and from core 0 to core 3 they all just remained at power saving - half the frequency. It was a matter of just clicking each applet and setting CPU scaling to "Performance" to watch the game run as fast as it used to before the update.
I couldn't believe it - why was CPU scaling set to 'Power Saving' on the first place? Is it the default setting? Why doesn't it switch automatically between power states?
This might have been "fixed" in the latest Release Candidates, though from the first Beta releases to TC6 from June 20th it was not...
