This is not correct.
If you care about every byte, you can make D code just as
performant.
And by caring about every byte, you'll need to become as
familiar with how D generates code, and the cost of what
various features entail, as you would be in C++.
Same can be said for JVM and .NET languages.
Some of our consulting projects are conversion of C++ code into
one of the said technologies. We usually achieve performance
parity with the existing application.
With C, C++ and Fortran it is easier to achieve a certain
performance level without effort, while the other languages
require a bit of effort knowing the runtime, writing GC friendly
data structures and algorithms, and doing performance analysis,
but it achievable as well.
Many developers don't want to do this, hence my statement.
