Would you care to address the questions about performance
raised in
the OP?
I thought I just did.
You made some generic statements about performance being good.
This is
obvious and undisputed. You did not answer any concerns raised
in the
OP. I am left to wonder if you even read it.
I did read it. Forgive me, but I don't have much new to answer
to it.
It seems you consider the lack of a long answer accompanied by
research and measurements offensive, and you also find my
previous answers arrogant. This, to continue what I was
mentioning in another post, is the kind of stuff I find
difficult to answer meaningfully.
Well, I don't want this to devolve to ad hominem level. I never
used the word offensive by the way, though I will admit to being
temporarily offended by your description of my carefully
constructed post as a self important rehash :)
Basically, I didn't find your reply useful because, as I said,
you were simply stating a generality about performance (which I
agree with), and not addressing any concerns at all.
If you don't have time to address this stuff right now, I
completely understand, you are an important and busy person. But
please don't give a generality or dodge the question, and then
pretend the issue is addressed. This is what I call arrogant and
it is worse than no reply at all.
w.r.t the one question about performance justification: I'm not
necessarily asking for research papers and measurements, but
based on these threads I'm not aware that there is any
justification at all. For all I know this is all based on a wild
guess that it will help performance "a lot", like someone who
optimizes without profiling first. That certainly isn't enough to
justify code breakage and massive UB injection, is it? I hope we
can agree on that much at least!
