proftp 사용중인데 접속이 느립니다.

proftpd-1.2.9 를 소스 컴파일하여 standalone으로 사용중입니다.

그런데 ssh, web 의 속도는 만족스러운데 반해 ftp는 접속시 시간이 굉장히 딜
레이됩니다.

일단 접속이 되면 업다운속도는 정상입니다.

레드헷 7.3이며 자체 네임서버는 운영하지 않고 호스팅업체에서 포워딩을 받고
있습니다.

여러 질문이나 답변을 보면서 이것저것 해보았지만 차이를 느낄수 있는 답을
얻지 못해 이렇게 질문을 드립니다.

우선 설정에 대한 부분을 보여드리면

proftpd.conf

# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use. It establishes a single server
# and a single anonymous login. It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.

ServerName "Happy"
ServerType standalone
DefaultServer on

# 기본 사용자 경로
DefaultRoot ~

# Port 21 is the standard FTP port.
Port 21

# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask 022

# To prevent DoS attacks, set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd).
MaxInstances 30

# Set the user and group under which the server will run.
User nobody
Group nobody

UseReverseDNS off
IdentLookups off

# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
#DefaultRoot ~

# Normally, we want files to be overwriteable.
<Directory />
AllowOverwrite on
</Directory>

# A basic anonymous configuration, no upload directories. If you do not
# want anonymous users, simply delete this entire <Anonymous> section.
<Anonymous ~ftp>
User ftp
Group ftp

# We want clients to be able to login with "anonymous" as well as "ftp"
UserAlias anonymous ftp

# Limit the maximum number of anonymous logins
MaxClients 10

# We want 'welcome.msg' displayed at login, and '.message' displayed
# in each newly chdired directory.
DisplayLogin welcome.msg
DisplayFirstChdir .message

# Limit WRITE everywhere in the anonymous chroot
<Limit WRITE>
DenyAll
</Limit>
</Anonymous>

/etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
ServierIP domain.co.kr Happy

/etc/sysconfig/network

NETWORKING=yes
HOSTNAME=localhost.localdomain

echo $HOSTNAME 해보면 localhost.localdomain 이라고 나옵니다.

ftp 사용이 빈번한 사이트라 standalone로 하였습니다.

전 네임서버쪽을 의심해 봤지만 ftp접속시에 아이피로 접속하기 때문에
