localhost vs domain for connection string

2010-11-23 Thread Brent Clark

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.


Kind Regards
Brent Clark

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 :-)

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

Table cache not being updated

2010-11-23 Thread Machiel Richards
Hi All

   Maybe someone can help me with this one.

We have set the table_cache to 1024, however the open tables
value stays 64 of 64.

Everything I checked stated that the open tables is related to
the table_cache variable.

Can someone please assist on why the value isn't being updated?

The MySQL version is 5.051a

regards
Machiel
