Overload resolution almost certainly takes a miniscule proportion of
compile time on any "real" program. Most lines have no overloading
at all.
As I mentioned, the only time I have ever seen it take a
measurable amount of time was on that amazingly long concatenation of
aggregates. So that case may be worth thinking about a bit, but for
the others, the key is to keep the overload resolution algorithm as simple
and understandable as possible. Chances are, unfortunately, that
"as understandable as possible" won't be very understandable ;-).
Especially if you try to keep predefined operators out of the
symbol table...
