Everybody is aware of the speed difference between Delphi and FPC.
The compiling itself (parsing/producing assembler code) is not slow.
From what I remember, the problems you (and everyone else) experience
with smartlinking and so on are largely due to the GNU linker being
slow and memory hungry.
AFAIK there are significant differences in parsing and code producing
too.
I suggest that Florian answers this, he has more exact numbers.
I see no way to speed up the 2.x FPC significantly only by stripping
something down or whatever. The whole 2.x design is geared towards
portability and maintainability, speed is only 2nd level goal (and being
honest, self compilation in ~10 sec even on my >5 year old Core 2 Duo is
not that bad ;)).
The only approach I see to speed it up is to kick the whole back end and
generate directly some close to i386 intermediate code directly in the
parser.
