In general, For[], Do[], and While[] loops are slower than their
functional equivalents in Mathematica.  You can probably do what you
want using Map[] and Table[].  Unfortunately the code you gave below 
is incomplete and makes no sense, so it's hard to say for sure.  Try
posting some more specific example code.  Thanks!
