This way you can pinpoint what needs upgrading. MySQL is a RAM hungry beast, so try to give it as much as you can. I’ve seen entry level xeon servers with SATA disks and large amounts of RAM (16GB) handle loads very well.

Also, never forget to tune your queries. Using the slow query log and EXPLAIN can help you find and fix bad queries. I’ve seen overloaded servers go to near idle by simply fixing a few queries. While this requires a lot of expertise, it can give you many-times the return as replication.

Not all applications can easily be switched to send read-only statements to the slave, so before deploying replication, be sure your application can effectively utilize your new slave server.
