Abstract: Traditional Linux file system such as ext2 performs poorly if large numbers of small files exist. This is due to the linear search algorithm of the file system. This paper implements SmallFS to solve this problem. SmallFS is one kind of storage optimization. It optimizes the search algorithm to greatly improve the performance. SmallFS is based on the stackable file system technique, so it has good compatibility and is transparent to users.

Key words: SmallFS, storage optimization, stackable file system

摘要： 当同一目录下存在大量文件时，对文件的线性检索造成传统的Linux文件系统(如ext2)性能有很大的下降。该文提出的SmallFS旨在解决该性能下降问题。SmallFS属于存储优化的一种，它对特定目录下的文件检索过程进行优化，能在较大程度上提高检索效率。此外，SmallFS基于可堆叠技术实现，具有较好的兼容性和对用户的透明性。
