The flags you want are -O, -inline -release.
If you don't have those, then that might explain some of the slow down

Lots of symbols and stuff.
You can get it down with -ffunction-sections -fdata-sections

Phobos should also be compiled with -ffunction-sections -fdata-sections to
get the whole effect though.

You don't need auto there.
