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 Sabrina

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).
