I haven't bothered too much about the performance effect of cashing, except some basic rules I follow without knowing why... 1) What happens if I access memory like this: for (; *p; --p, --q) *q = *p; will it be worse than this? for (; *p; ++p, ++q) *q = *p 2) Are there any cashing differences by accessing with pointers vs arrays? 3) Does register declaration affect cashing in any way? 4) What are the overall performance win in doing the cashing right? Thanks! //Peter
