In general gdc or ldc. Not sure how good vectorization is though, esp.
The flags you want are -O, -inline -release.
If you don't have those, then that might explain some of the slow down
on slicing, since -release drops a ton of runtime checks.
-noboundscheck option can also speed up things.

dmd is
I'd like to try d in computational physics. One of the most
appealing features of the d is implementation of arrays, but to
be really usable this has to work FAST.
So here http://dlang.org/arrays.html it is stated, that:
Implementation note: many of the more common vector
operations

auto-vectorization.
On the other hand the so called vector operations like a[] = b[] + c[];
are
