Now change compiler to icc and use -O3 or something.

Code now gets 2MB or so?

Yes your 1h3.pgn and 1h6always.pgn openingsbooks won't take up much space.

By the way you can still get your exe smaller when supercompressing it. It might
however take up to a few hours to supercompress it. And also a few hours to
uncompress it.

However the working set size is depending upon the datastructures you allocate.

As i have by default space for 16-32 processors in diep, i allocate several MB's
there at startup. Of course it heavily depends upon whether you use 64 bits code
or 8 bits code.

Note that i'm 32 bits.

Also software that's compiled in 64 bits for itanium2 will by default be up to 3
times larger than when compiled for x86.

Now i wonder how many megabytes the executable is of a simple TSCP program in
LISP...
