Opinions please : You can't (shouldn't) fix Stupid, remove the Stupid first and then see if you still have a problem.

So I was assigned a critical issue to fix... Something was failing to meet
it's real time deadline.

So I, obeying the principle of "Measure First, then guess", I plugged in a
bit of profiling code (hey this is in a very very tightly resource
constrained embedded device)... an lo and behold the most major consumer of
CPU and resources was a facility that doesn't (cannot possibly) exist within
this particular model.

Ie. The presence of this facility is just plain stupid.

Is it the cause of the issue?

Dunno, don't care. My working principle is don't fix Stupid, remove Stupid
and then see if you still have a problem... If you still have a problem fix
that without all the Stupid clouding the picture.

Now I'm aware that this deviates from more cautious types who would say,
prove first that the Stupid is causing a problem before you attack it.

My practice has always been, can't stand stupid, makes things complicated,
muddies the picture, if I see stupid The Big Cutting Tools come out and
Stupid goes and swims with the fishies.

Then I go back to being cautious.
