I'm considering shifting a large existing C++ codebase into D

log etc).
I've compared the raw speed of atan between C++ (Apple LLVM
version 7.3.0 (clang-703.0.29)) and D (dmd v2.079.0, also ldc2
1.7.0) by doing long loops of such functions.
I can't get the D to run faster than about half the speed of
C++.
Are there benchmarks for such scientific functions published
somewhere?
What compiled flags did you used to compile both C++ and D
versions?
