    I'm running CentOS 5.5 with vsftpd setup with an SSL certificate. I'm getting capped at about 180KB/s over a 1Gbps LAN connection. The same file to the same storage location with WinSCP runs at about 650KB/s. iptables is disabled on the server and the firewall on this Windows machine is set to allow all from FileZilla.

    Here is my vsftpd.conf:

    Code:
    # Example config file /etc/vsftpd/vsftpd.conf
    #
    # The default compiled in settings are fairly paranoid. This sample file
    # loosens things up a bit, to make the ftp daemon more usable.
    # Please see vsftpd.conf.5 for all compiled in defaults.
    #
    # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
    # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
    # capabilities.
    #
    # Allow anonymous FTP? (Beware - allowed by default if you comment this out).
    anonymous_enable=NO
    #
    # Uncomment this to allow local users to log in.
    local_enable=YES
    #
    # Uncomment this to enable any form of FTP write command.
    write_enable=YES
    #
    # Default umask for local users is 077. You may wish to change this to 022,
    # if your users expect that (022 is used by most other ftpd's)
    local_umask=022
    #
    # Uncomment this to allow the anonymous FTP user to upload files. This only
    # has an effect if the above global write enable is activated. Also, you will
    # obviously need to create a directory writable by the FTP user.
    #anon_upload_enable=YES
    #
    # Uncomment this if you want the anonymous FTP user to be able to create
    # new directories.
    #anon_mkdir_write_enable=YES
    #
    # Activate directory messages - messages given to remote users when they
    # go into a certain directory.
    dirmessage_enable=YES
    #
    # The target log file can be vsftpd_log_file or xferlog_file.
    # This depends on setting xferlog_std_format parameter
    xferlog_enable=YES
    #
    # Make sure PORT transfer connections originate from port 20 (ftp-data).
    connect_from_port_20=YES
    #
    # If you want, you can arrange for uploaded anonymous files to be owned by
    # a different user. Note! Using "root" for uploaded files is not
    # recommended!
    #chown_uploads=YES
    #chown_username=whoever
    #
    # The name of log file when xferlog_enable=YES and xferlog_std_format=YES
    # WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log
    #xferlog_file=/var/log/xferlog
    #
    # Switches between logging into vsftpd_log_file and xferlog_file files.
    # NO writes to vsftpd_log_file, YES to xferlog_file
    xferlog_std_format=YES
    #
    # You may change the default value for timing out an idle session.
    idle_session_timeout=600
    #
    # You may change the default value for timing out a data connection.
    data_connection_timeout=120
    #
    # It is recommended that you define on your system a unique user which the
    # ftp server can use as a totally isolated and unprivileged user.
    #nopriv_user=ftpsecure
    #
    # Enable this and the server will recognise asynchronous ABOR requests. Not
    # recommended for security (the code is non-trivial). Not enabling it,
    # however, may confuse older FTP clients.
    #async_abor_enable=YES
    #
    # By default the server will pretend to allow ASCII mode but in fact ignore
    # the request. Turn on the below options to have the server actually do ASCII
    # mangling on files when in ASCII mode.
    # Beware that on some FTP servers, ASCII support allows a denial of service
    # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
    # predicted this attack and has always been safe, reporting the size of the
    # raw file.
    # ASCII mangling is a horrible feature of the protocol.
    #ascii_upload_enable=YES
    #ascii_download_enable=YES
    #
    # You may fully customise the login banner string:
    ftpd_banner=Welcome to InSayne LAN FTP service.
    #
    # You may specify a file of disallowed anonymous e-mail addresses. Apparently
    # useful for combatting certain DoS attacks.
    #deny_email_enable=YES
    # (default follows)
    #banned_email_file=/etc/vsftpd/banned_emails
    #
    # You may specify an explicit list of local users to chroot() to their home
    # directory. If chroot_local_user is YES, then this list becomes a list of
    # users to NOT chroot().
    #chroot_list_enable=YES
    # (default follows)
    #chroot_list_file=/etc/vsftpd/chroot_list
    #
    # You may activate the "-R" option to the builtin ls. This is disabled by
    # default to avoid remote users being able to cause excessive I/O on large
    # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
    # the presence of the "-R" option, so there is a strong case for enabling it.
    #ls_recurse_enable=YES
    #
    # When "listen" directive is enabled, vsftpd runs in standalone mode and 
    # listens on IPv4 sockets. This directive cannot be used in conjunction 
    # with the listen_ipv6 directive.
    listen=NO
    #
    # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
    # sockets, you must run two copies of vsftpd whith two configuration files.
    # Make sure, that one of the listen options is commented !!
    listen_ipv6=YES
