NSS = Name Service Switch.  /etc/nsswitch.conf controls how your system
gathers/validates information about a variety of things including:

DNS
Service
User Database (Numeric User ID, Username, home directory, etc)
Authentication Database (/etc/passwd, /etc/shadow)

If you implemented and LDAP Authentication system you would enter the
value "ldap" into your nsswitch.conf for passwd and shadow rather than
the default which is assumed to be "file" unless something else is
explicitly defined.

The resolv.conf file controls who your name servers are (mine is
127.0.0.1 on my desktop since I run BIND 9) and what the search domains
ought to be (if I enter just "www" as a host name, what domains should I
search for "www" in?).

Commonly used hostnames (such as localhost and the name of your system)
should be defined in /etc/hosts file to avoid uneeded and costly DNS
Lookups.

Does it say anything about using DMA?  If it says you are using DMA then
it is already using the fastest speed that it can.
