Trace Analysis,Trace analysis provides insights into workload properties and IO patterns, which are essential for storage system tuning and optimizing. This chapter discusses how the workload interacts with system components, algorithms, structures, and applications.

After capturing the pattern, I developed a synthetic emulator to match the real traces. The second tool is PCMark from FutureMark. I illustrate how to use gain-loss analysis to improve cache algorithm efficiency.
