In this paper, we are investigating a claim about the performance of the Linux ext2 file system under streaming I/O. A look on the ext2 does reads and writes is presented together with an extensive testing of the file system performance under streaming reads and writes. The tests aim at comparing the performance of ext2 with that of the raw performance of the underlying storage device.
The results of the benchmarks show no evidence of a problem in ext2 performance. Ext2 is able to exploit the full bandwidth of the underlying storage device in both reading and writing at its worst case; that is, without the help of its buffering techniques.
