Is my mod_cband working ?

[izumi777]

I install mod_cband on apache server running on linux CentOS

I put these directives on the files
/usr/local/directadmin/data/templates/custom/virtual_host2.conf

<VirtualHost |IP|>
ServerName www.|DOMAIN|
ServerAdmin |ADMIN|
DocumentRoot |DOCROOT|
CBandScoreboard /var/www/scoreboard/|DOMAIN|.scoreboard
CBandSpeed 1536 15 30
CBandRemoteSpeed 728kb/s 3 3
</VirtualHost>

Then I echo "action=rewrite&value=httpd" >> /usr/local/directadmin/data/task.queue
and restart apache

But when I look at the mod_cband status page
why does the Remote clients still have speed more than 728kbps
and the request per sec is also above 15.
