we are trying to transfer from our data center to aws. In both situations we have a few web servers with one master and two slave databases. We had to pull the switch monday back to the data center though. The ec2 mysql slaves were taking between 40 and 140 seconds to execute the homepage queries that take 1s tops from our data center. We are using 1 large and 1 xl slave, which should be actually a little more powerful than what we have in the datacenter. During that time our slave ec2s had a solid 100% cpu level. They have mounted ebs volumes. Anyone have any ideas what's going on here?
