The idea behind this is to speed up cluster resources such as garbage collection, reduce image transfer over the network, and accelerate the application launch. A simple sysbench benchmark on MySQL shows an overhead between six and 10 percent on CPU-bound systems when running perf with the default sampling frequency of 4000 Hz.

Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. With the proper battery backup and algorithms, the hardware write cache can secure the data safely (on stable media) as well as increase the speed of an application like SQL Server by hiding much of the true physical I/O time.
