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.

localhost vs domain for connection string
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. Hence the reason im asking But the real reason is that the first clients machine is under heavy load and we are trying to see what can be improved.
