Wow - saturating a 100Mb link with mysql seems a little excessive to me. 
Surely myth only needs to transfer the metadata?  I look after 
production mysql databases that do 100 queries a second over 100Mb ethernet.

There has to be a lot of traffic going over the wire on the myth protocol.

Might be worth capturing using tcpdump and replaying with etheral to see 
what all that chat is?
