A storage performance analysis tool is crucial to finding performance bottlenecks in I/O storage systems and developing efficient storage system architectures or algorithms. Due to the existence of many parallel Linux projects, there are also many trace tools proposed by different authors. This paper presents an integrated performance analysis tool for Linux file systems. The tool provides actual time information for Linux file system functions. In contrast to other existing tools, the tool provides a filtering mechanism, a graphical interface and system-level analysis information without a heavy load of measurement.
