Elapsed time and cpu usage are too different things. Sendmail tries
to deliver an entire list of addresses in sequence in a single process
so using bulk mailer or tlb speed things up by splitting the list
into several chunks that are delivered simultaneously by different
sendmail processes which will increase the cpu load. However, one
thing that should always help is to run a caching nameserver on the
same machine that is performing delivery.
