In my humble opinion this is because TeX manages memory by it self... and maybe a 64bit memory word of packed data uses twice of memory as 32bits one.... I am not sure.

well, the fact that linux 64 bit runs much faster contradicts that

one thing that we observed is that the lua garbage collected performs different on different platforms / architectures / cpu cache etc

Another way to get a speed penalty is when the exe 64-bit but some of the libraries it (or the operating system) needs to use are 32-bit. Best wishes, Taco
