I made the following performance test, which adds 10^9 Double’s
on Linux with the latest dmd compiler in the Eclipse IDE and
with the Gdc-Compiler also on Linux. Then the same test was
done with C++ on Linux and with Scala in the Java ecosystem on
Linux. All the testing was done on the same PC.
The results for one addition are:
D-DMD: 3.1 nanoseconds
D-GDC: 3.8 nanoseconds
C++: 1.0 nanoseconds
Scala: 1.0 nanoseconds
D-Source:

Compiler settings for D:

So what is the problem ? Are the compiler switches wrong ? Or
is D on the used compilers so slow ? Can you help me.
Sources and command lines for the other languages would be nice
for comparison.
