VSFTPD user limits?

[wolfr1]

Is there a way to limit individual bandwidth or sessions for users? Most of my users are fine but server limitations that I've put in place for the sake of a few are really hampering the rest. Can I limit individual user sessions and/or available bandwidth with VSFTPD? I haven't found a way to do this...

Looks like my Google-fu wasn't strong...I've found this:

In order for virtual user configuration of vsftpd to take effect, here is what you need:

* user_config_dir=/etc/vsftpd/users

* one file per user with filename identical to the username, so for example, if you want a user janedoe to login and have personalized settings for her, create file /etc/vsftpd/users/janedoe

* do chown root.root /etc/vsftpd/ -R

* /etc/vsftpd/users/janedoe, you can do stuff like:
anon_mkdir_write_enable=NO
anon_other_write_enable=NO
anon_upload_enable=NO
dirlist_enable=YES
download_enable=YES
local_root=/www/janedoe
write_enable=YES

For simplicity sake, I am posting a complete working configuration:

anonymous_enable=NO
local_enable=YES
write_enable=YES
anon_upload_enable=NO
anon_mkdir_write_enable=NO
anon_other_write_enable=NO
chroot_local_user=YES
guest_enable=YES
guest_username=ftp
listen=YES
background=NO
listen_port=21
pasv_min_port=30000
pasv_max_port=44444

### Custom Configuration ###
user_config_dir=/etc/vsftpd/users
dirlist_enable=YES
download_enable=YES
connect_from_port_20=YES
hide_ids=NO
use_localtime=YES
virtual_use_local_privs=YES
xferlog_enable=YES
async_abor_enable=YES
local_umask=022
port_enable=YES
port_promiscuous=NO
setproctitle_enable=YES
anon_max_rate=1
max_per_ip=6
max_clients=6

However I am curious if once I add that to a config for one user to ALL users have to have a config?
