This is something to check out before you attempt to attack the problem by
changing /etc/hosts:

Be sure that you do not have an /etc/resolv.conf file.  If you have one, and
especially if you have an entry to a nameserver in there, this could account
for the delay: it will cause the systems resolver routines to query the
nameserver before it looks in /etc/hosts.  It has to wait for an answer from
the nameserver first.  AIX resolver routines will, (unless you tell it
otherwise through /etc/netsvc.conf or the NSORDER environmental variable)
use  DNS first IFF /etc/resolv.conf exists.
