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.
