Now, I don't want to start a religious war, but... cool a religious war...
A quick google shows that most of the discussion on these things took place years ago (2001-2003) & not a lot thats current, so its hard to know what still applies.
People I know who've used Reiser say it's wonderfuly fast, but if it
corrupts, well... save your time, and go straight to restoring your backups.
ReiserFS does seems just like the ducksnuts in terms of performance, but it seems to have accumulated some horror stories along the way: http://www.linuxsa.org.au/pipermail/linuxsa/2002-January/038035.html
Marcs being runing it for 5 years, no issues - any one else using it?
It also seems a non-trivial to convert an existing ext3 install. I don't have hands on access to the box ($75 for remote hands on), so resizing the partition, convertfs to new partition, rebooting, deleting old partion resising new partion all seems a bit daunting when I cant actually sit at the console JIC if I stuff up along the way.
If I'm going to go to that effort, I should probably contemplate xfs and jfs and make best choise first up - anyone got any experience with these where maildir is concerned?
Also, take a look at the tune2fs options. I understand -O dir_index
will set it to use a b-tree index for faster handling of large directories.
Check this out relating to this option: http://www.namesys.com/benchmarks.html I haven't fully digested but it seems that ext3 doesn't get close, + there are other caveats.
All this information is quite old, and I wonder whats changed since then, both for rieser and ext3, also [xj]fs, which were considered pre-natal when most of these were written.
So is anyone out there using ext3 with our without dir_index for significant maildir imap installs and just delighted with it?
Thanks all Glenn

Actually - yes. Same problem. But the solution is to use the Reiser Filesystem. It doesn't have the ext3 problem.

Ext2 has the advantages that 1) it can fall back to ext2 in recovery cases, and 2) because of that, it has all the well-tested ext2 recovery tools available.

I've been using it for 5 years and it works great. It specifically eliminates the speed problems of Maildir where you have thousands of files in a single directory. And it has infinite inodes so you never run out of them. Reiser is ideal for email systems.
