What channel are you using?
What is your setup? Does the multicast traffic is sent from STA to AP or 
the opposite ?

Unicast traffic is controlled by the rate control algorithm, trying to 
achieve the best performance.
Multicast traffic is not under the rate control algorithm and since it 
cannot be retransmitted, nor ACKed, it is transmitted at 1 Mbits rate in 
802.11bg and 6 Mbits rate in 802.11a.
