--- Comment #1 from Armin Le Grand <Armin.Le.Grand at me.com> ---
In this task I'll try to take some into account on weak HW where we know no
special Graphics-HW is available and also CPUs are not breathtakingly powerful
(good test is to build LO).
Taking care of this is one thing, but...
- Need to take care on all possible scenarios
- No use to optimize one case and kill a dozen others
- Only valuable when not influencing other system-dependent parts
- System-independent parts might not be prevented to use better stuff/paths in
SW when available

There are various possibilities to try to put the lever at. It is clear that
quite some security aspects (in the sense of not killing other scenarios) and
thus experimenting/testing will have to be done. It is quite possible that more
than one and/or combinations of activities/changes will lead to success. There
are also already some, which are more or less successful in diverse scenarios.
I will number the things that come to my mind and I will investigate in and try
to document possible enhancements/progress here. I will also show some which
seem plausible but do not work well.
