This document presents information about filesystems and their test results.
Overview of the Filesystems
- Ext2 was originally released in January 1993.
- Ext3 adds journalling to Ext2 so that an fsck does not need to be performed during startup in the event of an unclean shutdown.
- JFS is developed by IBM. JFS is a stable and high performance filesystem that provides fast filesystem restart in the event of a system crash.
- XFS is a high performance journaling filesystem which originated on the SGI IRIX platform. It can support large files and large filesystems, extended attributes, variable block sizes, is extent based, and makes extensive use of Btrees (directories, extents, free space) to aid both performance and scalability. Also see http://oss.sgi.com/projects/xfs/.
Benchmark Utillities
In this section the Bonnie benchmark will be shown. Bonnie is a program that plays with filesystem bottlenecks. At this point with this tests suite can be achieved different sides of the testing filesystem and its bottlenecks. With analysis of the report made by Bonnie it can find out where the filesystem has strong and weak sides.
For an explanation of the numbers below, see bonnie.
Benchmark Test Results
Creating the filesystem with
mkfs.ext2 -b 1024
The used Bonnie options were -s 256. The used mount options for local fs were rw,noexec,nosuid,nodev,user=hydraj.
Ext2 Filesystem with Block Size = 1024
In followed report are included date, mount options, and report from bonnie benchmark. Included are test file size and number of processes used in parallel too.
