Abstract
The Linux kernel is unique in
that it supports a wide variety of high-quality filesystems. For server systems, the most commonly used
are Ext2, Ext3, ReiserFS, XFS and JFS.
This paper compares the performance of these filesystems using Linux
2.4.17 and three benchmarks: pgmeter, an open source implementation
of the Intel Iometer benchmark; filemark
(a version of postmark); and AIM Benchmark Suite VII.
The benchmarks were run on three different
systems ranging in size from a contemporary single-user workstation to a
28-processor ccNUMA machine. Although
the best-performing filesystem varies depending on the benchmark and system
used, some larger trends are evident in the data. On the smaller systems, the best-performing file system is often
Ext2, Ext3 or ReiserFS. For the larger
systems and higher loads, XFS can provide the best overall performance.
