S3FS[1] is an interface implementation using FUSE and Amazon Storage Services in order to provide a reliable and secure storage location with a easy to use interface for Unix users. Although S3FS[1] presents a simple and functional implementation, there are several issues, inherent to WANs(Wide Area Network), not considered during its implementation.

This project explains some of the limitations of the current S3FS[1] implementation and addresses the performance issues with a simple solution based on existing designs and algorithms. Due to the high latency of the WANs, this project will implement an asynchronous Caching mechanism along with parallel processing of the Reads/Writes requests to S3, therefore mitigating the performance loss caused by the latency of the wide area networks.
