Like poor buggy SATA performance in K/Ubuntu?

Like useless heavy debug messages junks from almost all KDE applications
pushed along pipelines and written back to disk in file .xsession-errors
each time you use a KDE program?

Maybe that stupid default atime update that imply you need to know when
each single file has bean read? (do you?)

Or maybe that SVG rendering engine that suck memory and CPU each time it
update a damaged region after a window move, just because you have a
very nice Hardy Heron SVG drawing as your desktop background?

I agree, there are things users can do to improve performance in
Kubuntu, like avoiding SVG backgrounds.

There are other things like SATA slowness, poor choices in default mount
options that require wise knowledge to be fixed.
