Using the right file system is one of the most critical factors in achieving system performance, and also the most often overlooked. This is true for desktops, servers and even more so for embedded devices. This paper will look at a more efficient way of achieving the device responsiveness—improving data management performance by using a highly optimized file system. The paper will first evaluate file system architectures based on certain key constructs that have significant impact on its performance and then provide an overview of a new file system that employs these constructs.
