Xfce is very slow, part 2

I'm sorry, I have not digested everything in this thread, but I have seen
this symptom and on my laptop it is almost always due to power saving
features keeping the CPU going slow, even when you don't want them to.  The
cpufrequency controls are, well, almost diabolically complicated and the
daemons don't always do what you expect, the documentation on what to do is
really confusing and inconsistent.

For me, using either Debian or Ubuntu, the cpufrequency  up_threshold gets
stuck at system minimum, and even if you think you have re-set that, it
still goes back. I think the Mint linux documentation on this is best, but
here's the gist of it.

Suppose your governor is the "ondemand" governor.  Look at this



pauljohn at dellap7:~$ sudo cat
[sudo] password for pauljohn:

If it is set at 95, it means your system stays slow until its use is over

Manually lower that, allowing the CPUs to scale up more aggressively

$ su -c  "echo -n 70 >

I'm stunned by the difference on my Dell Precision M4600.  It is like
walking in jello, then speedy.
