I was hoping to beat my dear Python and get similar results to

Try using ldc2 instead of dmd:
```
ldc2 -O3 -release -boundscheck=off -flto=full
-defaultlib=phobos2-ldc-lto,druntime-ldc-lto speed.d
```
should produce much better results.
It did! Tried those flags with dmd and ldc and got the following
