Even if the compiler produces executables which are far smaller than the
competition for real projects? Your benchmark is meaningless. If you
want to work with no support for a "Hello World" .exe, then don't use
the VCL or RTL. Code it all from scratch. If you want to get some work
done, stop worrying about your .exe size.

I recently had a play with the Free Pascal Compiler and Lazarus, and
was quite impressed so I decided to throw the source of my Suduko
solving program at it to see just how good/bad it was.

First the code compiled first go, no changes required, but the exe was
huge 6meg compared to 400K in D7... So then I decided to do some speed
tests, it might produce huge code (which I could probably trim down
myself with a bit of hand optimising) but blimee does it run fast.
Running my program and solving a 4x4 hex suduko was 3x faster with the
FPC code than D7.

FYI my suduko program uses some huge tlists and self calling
functions, so it looks like FPC is faster with it's tlist handling,
although I haven't checked to see if it's greedier with the memory
when running.

Moral of this story, if you program is 15x bigger, but runs 3x faster,
are you going to complain?

Dodgy.
