1. You are a professional level SQL Sever 2008 Database Administrator.
An instance runs on a computer, and the computer has eight quad-core processors and 128-GB RAM. The instance is utilized by four different applications. Not only a low number of CXPACKET waits but also a large number of lazy writer waits are experienced by the instance. The performance of the instance should be optimized.
