Use ldc, rdmd can invoke it for you. DMD's optimizer is not
even close to as advanced as a modern JavaScript engine's -
that's why we use it for fast build times instead of
performance.
Impressive performance increase:
$ ldc2 -O -release --run sorted.d
# D
1.0M: 810 ms
1.5M: 1324 ms
3.0M: 2783 ms
6.0M: 5727 ms
Thanks Max
