No doubt starting a long and detailed discussion about what the question
was asking and all the different interpretations but...
"Users in vlan46(btw r4&r6) have been complaining about slow ftp
trasfers
when accessing servers behind BB1"
The actual file transfer component uses TCP/20, whereas the FTP control
takes TCP/21. Prioritizing control traffic will only accelerate the
ability of uses to execute commands, but it won't help the actual speed
of data transfers.

Can I ask why for an Active FTP session you match for FTP-DATA only?
I know the lab solution does that as well, but in my understanding of
Active FTP the client opens a control session to port 20 and then the
server opens a data connection from port 21 (ftp-data) to the
destination port provided by the client.
But the control connection to the FTP server port 20 carries
bidirectional traffic, so IMHO the "ftp" traffic should be matched as
well.
i.e.
queue-list 1 protocol ip 1 tcp ftp-data
queue-list 1 protocol ip 1 tcp ftp

Think of the CQ byte-count as weights; with that configuration FTP will
send 1000 bytes of every 10000 bytes of total traffic (9000 + 1000). So
FTP
will always send 10% of the total traffic (1000/10000) regardless of the
interface's speed, which in this case is 100Mbps (10% = 10Mbps).
