Performance

Hi All

I've just started a new job and noticed that the analysts computers are connected to the network at 100Mbps. The queries we run against the MySQL server can easily be 500MB+ and it seems at times when the servers are under high load the DBAs kill low priority jobs as they are taking too long to run.

My question is this... How much of this server time is spent executing the request, and how much time is spent returning the data to the client? Could the query speeds be improved by upgrading the network connections to 1Gbps?

Thanks Rob
