Are you sure that this is a samba issue and not a Solaris issue?  You may
want to turn process accounting on (see acct(1M)) to see if the processor
is being used by smbd, in.lpd, lpsched, etc.  Also, with that number of
queues, if you do not have enough RAM to cache all directory entries and
lots of files in /var/spool/print you may be getting killed by file system

Without the interaction of Samba, our old print server, an Ultra 2 with (I
think) 128 MB of RAM carried a constant load of around 3.5 and was quite
unresponsive to interactive users.  Upgrading to 384 MB of RAM reduced the
load and made it much more responsive.  Upgrading to a Netra T1 with 512 MB
of RAM made the load drop to about .25 and you cannot tell that anything is
happening on it.
