Oh yeah. Orders of magnitude, easily.

The slowness is not in any way
inherent to CTFE. The experience will be completely different, once I have
some time to work on it -- I know exactly how to do it.
Did 2.058 or 2.059 see any new code for CTFE? Like the OP, I've the
impression CTFE/mixins suddenly became far slower. I'm not
complaining, I understand it's a difficult part of DMD, but I wondered
if what I see is real or imaginary.
The behaviour of __traits(allMembers) changed (it now returns an array
of string literals) and I expect that to be a little bit slower.
Compiling Phobos is now *much* slower than it used to be, due to changes
in Phobos. (eg, import std.random; is unbelievably slow).
As for CTFE, certain cases became faster (eg, repeated use of global
array literals).
But if you can pinpoint a case where CTFE itself became slower, I'd like
to know.
