Subject: pointer and 64 bit

Hi,

my question, why are instructions with pointers and arrays in 64-bit mode much
more slow, than in 32-bit mode?

code, like

dist=distance[from][to];
....

gets extremely slow, when compiled in 64-bit mode, while the most other
operations are more efficient under 64-bit mode!??
