Using 'localhost' will always be faster, although perhaps imperceptibly so.

Re: localhost vs domain for connection string
IIRC, "localhost" is seen by the client as a magic word to mean "use the UNIX socket, not 127.0.0.1". So, yes, that would make the connection not show up in netstat :-) On Tue, Nov 23, 2010 at 11:11 AM, Brent Clark wrote: > Hiya > > Is there a difference if someone had to make the connection string the a > domain (hosts file entry makes the machine look at its ip) as opposed to > just using localhost. > If so would a performance hit be incurred? > > I have this client that has used the domain and in netstat im seeing all > this > > tcp0 0 own.ex.ip:50340 own.ex.ip:3306 ESTABLISHED > 30324/apache2 > tcp0 0 own.ex.ip:50287 own.ex.ip:3306 ESTABLISHED > 30309/apache2 > tcp0 0 own.ex.ip:3306 own.ex.ip:50287 ESTABLISHED > 29234/mysqld > tcp0 0 own.ex.ip:50357 own.ex.ip:3306 ESTABLISHED > 31714/apache2 > tcp0 0 own.ex.ip:3306 own.ex.ip:50335 ESTABLISHED > 29234/mysqld > > But I have another client that is using localhost and netstat is quiet as a > mouse. > > This actually never dawned on me.
