There'd have to be no nulls, period, to get any useful performance
difference --- but yes, in theory putting fixed-length columns before
variable-length ones is a win.
I wouldn't bother going out to rearrange your schemas though ... at
least not before you do some tests to prove that it's worthwhile.
