mysql performance

[Ray]

Hello all;
I found this comment on the php website:


If you are experiencing extremely slow connections to MySQL from PHP from
a Windows 2003 Server it may well not be PHP or IIS - try loading mysql in
in 'skip-name-resolve'-Mode. 

It may mean the difference between a 10 second load time and a split
second load time.
(source:  http://ca3.php.net/mysql)

is there any truth to this, and if so, how do I do this?
