The place where the difference will really being to show up is when the filesystem has been used for a while, and starts to become fragmented. Filesytems like XFS trade time when creating a file for time reading it, on the grounds that reads usually happen a lot more than writes (e.g., you create a web page once; it then gets read lots of times, once for each query). So by spending more time placing the file at creation time, it can get better overall performance. So *if* you're doing tests on FS performance, please prefragment the filesystem by playing some standard pattern of file creations and deletions before running your tests.
