Haskell is the language that everyone loves to learn and talk about, and
few actually use.
And it's significantly slower than D,
(Sufficiently sane) languages are not slow or fast and I think the
factor GHC/DMD cannot be more than about 2 or 3 for roughly
equivalently written imperative code.
Furthermore no D implementation has any kind of useful performance for
lazy functional style D code.
In some ways, D is very significantly slower than Haskell. The
compilers optimize specific coding styles better than others.
in unfixable ways.
I disagree. That is certainly fixable. It is a mere QOI issue.
Actually, a factor of 2 to 3 can be huge.
Sure.
Consider that java is around a
factor 2 or less to C++ in the Computer Languages Benchmark Game, and
yet, you easily feel the difference everyday on your desktop applications.
Most software I use is written in C or C++. I think some of it is way
too slow.
But although the pure computation power is not very different, the real
difference I believe lies the memory management, which is probably far
less efficient in Java than in C++.
It still depends heavily on how well it is done in each case.
