Using the New Linux ReiserFS Filesystem - Page 3

In the case of the single 200 MB file, ReiserFS and ext2 were pretty similar. But for the small file manipulations, ReiserFS was much faster. Also note the difference between random and sequential deletes in ext2.

I also killed the power on the system a number of times without shutting down properly, and the ReiserFS partitions were checked and back online in less than a second when the system came back up. On the other hand, the ext2 partitions took 20 to 40 seconds to run e2fsck.

Real-World Usage

The following statements were listed as testimonials on the ReiserFS Web pages. SourceForge is a developer resource that sponsors open source projects; the site is run by VALinux. Mozilla is the open source spin-off from the commercial Netscape browser:

  • "http://ftp.sourceforge.net/ has 850GB storage, half of which is reiserfs, half is ext2. Both filesystems have been running flawlessly for > 4 months of production (actually longer, but wasn't reiserfs before). That server pushes between 15Mbit and 50Mbit/sec, and pulls/syncs about 2-5Mbit/sec, 24x7."

  • "Reiserfs also powers the CVS tree filesystem for cvs-mirror.mozilla.org (also tokyojoe.sourceforge.net), which is the one and only anonymous CVS checkout point for mozilla. That server has run flawlessly under very heavy load since birth."


I hope this overview gives you some insight as to the pros and cons of using ReiserFS. My experience so far has been good, and I may adopt it the next time I upgrade my server. In the meantime, I'll continue running it on this test system, and perhaps load up a database and give it a bit more of a workout. //
