The trick to getting decent performance with NetView using AIX 4.3.3 is to add 
the following entry in the /etc/netsvc.conf file on every AIX host including 
the NetView server (assuming it is AIX):
hosts=local4,bind4

This means that AIX 4.3.3 will use IP ver 4, which it eventually does after 
first trying IP ver 6 and then timing out to drop back to ver 4.  This is the 
reason for the slowness.

One further matter.  When using DNS on an AIX server, make certain that 
/etc/hosts only contains entries for the local loopback and all host adapters, 
nothing else.  This results in the shortname appearing as the ipadapter label 
and not the fully-qualified domain name.  The shortname will resolve through 
DNS.
