We have an implementation of KQML that we've developed here at Lockheed Martin in
collaboration with the LAIT group (Tim Finin's group) at UMBC.  We've done
benchmarking of transmission of "small-size" messages (up to 10K), "medium-size"
messages (10K-100K) and "large-size" messages (1M-10M) between two agents.  Our
round trip time for small messages is (worst case) just under .4 seconds/msg. 
Transmission rate for our large messages averages out to around 670Kbytes/second,
so we believe that KQML can be pretty fast.
