pureftpd问题

状况如下:
装好后,ftp上传下载速度不超过30k,系统用户也是如此.配置文件如下

http下载可以达到700K因此,网络应该没有问题

pureftpd配置文件如下..不知道是什么因素限制了速度

############################################################

# If you want to run Pure-FTPd with this configuration
# instead of command-line options, please run the
# following command :
#
# /usr/local/sbin/pure-config.pl /usr/local/etc/pure-ftpd.conf
#
# Please don't forget to have a look at documentation at
# http://www.pureftpd.org/documentation.shtml for a complete list of
# options.

# Cage in every user in his home directory

ChrootEveryone yes



# If the previous option is set to "no", members of the following group
# won't be caged. Others will be. If you don't want chroot()ing anyone,
# just comment out ChrootEveryone and TrustedGID.

TrustedGID 50



# Turn on compatibility hacks for broken clients

BrokenClientsCompatibility yes



# Maximum number of simultaneous users

MaxClientsNumber 50



# Fork in background

Daemonize yes

# Maximum number of sim clients with the same IP address

MaxClientsPerIP 8



# If you want to log all client commands, set this to "yes".
# This directive can be duplicated to also log server responses.

VerboseLog no



# List dot-files even when the client doesn't send "-a".

DisplayDotFiles no



# Don't allow authenticated users - have a public anonymous FTP only.

AnonymousOnly no



# Disallow anonymous connections. Only allow authenticated users.

NoAnonymous yes



# Syslog facility (auth, authpriv, daemon, ftp, security, user, local*)
# The default facility is "ftp". "none" disables logging.

SyslogFacility ftp



# Display fortune cookies

# FortunesFile /usr/share/fortune/zippy



# Don't resolve host names in log files. Logs are less verbose, but
# it uses less bandwidth. Set this to "yes" on very busy servers or
# if you don't have a working DNS.

DontResolve no



# Maximum idle time in minutes (default = 15 minutes)

MaxIdleTime 15



# LDAP configuration file (see README.LDAP)

# LDAPConfigFile /etc/pureftpd-ldap.conf



# MySQL configuration file (see README.MySQL)

MySQLConfigFile /usr/local/etc/pureftpd-mysql.conf


# Postgres configuration file (see README.PGSQL)

# PGSQLConfigFile /etc/pureftpd-pgsql.conf


# PureDB user database (see README.Virtual-Users)

# If you want to enable PAM authentication, uncomment the following line

# PAMAuthentication yes



# If you want simple Unix (/etc/passwd) authentication, uncomment this

UnixAuthentication yes


# Please note that LDAPConfigFile, MySQLConfigFile, PAMAuthentication and
# UnixAuthentication can be used only once, but they can be combined
# together. For instance, if you use MySQLConfigFile, then UnixAuthentication,
# the SQL server will be asked. If the SQL authentication fails because the
# user wasn't found, another try # will be done with /etc/passwd and
# /etc/shadow. If the SQL authentication fails because the password was wrong,
# the authentication chain stops here. Authentication methods are chained in
# the order they are given.

# You can also only allow a non-routable local IP (like 10.x.x.x) to
# authenticate, and keep a public anon-only FTP server on another IP.
