안녕하세요.

unauthenticated user 겁나 많을때

web db 서버 나눠서 사용하는 경우에 

web서버에서 db서버로 resolving 요청하는데 정상적으로 대답이 안되면 커넥션을 유지한다. 그래서 느려짐

# CentOS-Base.repo

#

# This file uses a new mirrorlist system developed by Lance Davis for CentOS.

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the 

# remarked out baseurl= line instead.
