This is the default on windows x64.

Well, some poking aronud by the sysadmins and they found teh perl
was compiled with

 MYMALLOC PERL_MALLOC_WRAP USE_64_BIT_ALL USE_64_BIT_INT USE_FAST_STDIO
 USE_LARGE_FILES USE_PERLIO

So it was using 64 bit variables for INT and maybe some other uneeded
things.
So that might be a big part of it.

 Good question. While I haven't made the jump to 64bit for my web
 machines there are lots of memory related things that double in size
 when you do so. I wouldn't expect it to be a full 2X jump, so something
 else might be amiss. Besides the 32v64bit change is all the other
 software the same?

Does anyone know if one can have 64bit perl use 64 bit addressing (to make
use of 4GB RAM) but still use 32-bit INTs etc (to keep footprint from

I should add - if anyone can answer this question - would it be a good idea
to do
so even if possible?

Thanks,
