>Work around slow DNS

>If you have a slow DNS server that is causing you delays, for example while browsing the web, then try switching to a faster DNS server.

If that does not work, then here’s a trick you may want to try: make your computer perform DNS lookups for the hostnames you use most often (such as www.google.com) on a regular basis.

On Mac OS X, Linux and UNIX systems this can be accomplished using a simple cron job, just execute a command like:

nslookup http://www.google.com

or:

host http://www.google.com

This will perform the DNS lookup, and -as a side-effect- add the result to the local DNS cache.

 

>Improve DNS lookups on your Mac

>Here’s a quick tip for Mac OS X users that want to speed up their DNS lookups. If you don’t get annoying ‘Looking up server’ messages frequently, you’re safe to skip this one:

• Speed internet browsing via a local domain server [macosxhints.com]

Warning: This is only for power users (those that know what UNIX and Terminal are about).
