  Well, if he wants to waste money....  10 to 15K accounts is not a lot
accounts.  Plus, "Sun big iron" comes with such slow processors.  For
instance, the 2.4Ghz Xeon is going to be faster than any single Sun
processor.  You'll need a quad Ultrasparc to keep up with a basic dual
Xeon (like Dell Poweredge 2650).

  My /etc/master.passwd has 27,500 entries.  This is on a dual P3-1Ghz.
It is not really loaded.  I will run out of disk space before, the CPUs
get bogged down.
