> The benchmarks where Fortran is much slower than C/C++ involve processes where most of the time is spent reading and writing data, for which Fortran is known to be slow.
Why would IO be slow in any language? What does the language have to do besides buffering and system calls?
> In Fortran, variables are usually passed by reference, not by value. Under the hood the Fortran compiler automatically optimizes the passing so as to be most efficient.
Aren't arrays implicitly passed by reference in C also?
