I find that surprising.  Majordomo is not a cpu intensive process.
If the list is very active, then it might be simply be sending a lot
of mail and leaving a backlog in the mailq, but those sorts of
things can usually be tuned for.

It would be, if the accusation were true.  I find it extremely doubtful.

I think the primary concern for large or active lists is how quickly
mail passes off your system.  That is really where any bottle neck
will be.  See if it is possible to ask for clarification about
the cpu usage.  My guess is someone mumbled something about "resources"
and someone else reported that as "cpu".
