question about tc command

Hello,

I´m trying to manage the bandwidth of my adsl connection with the
command tc. (htb.init)
I have made two bands, one for ftp data and the other band for the web.
I have 2Mbit/300kbit adsl and I have set the ceil of the bands to
300kbits. I thought that when I have ftp data and http data i´ll get the
half of the bandwidth to each connection, but the ftp connections gets
all the band and the http gets very very slow. I have set priority 0 to
the web band and 1 for the ftp band, but it doesn´t solve anything

What I´m doing wrong? any idea?
