Hi all,
In last year, i had made some research and benchmarks based on CentOS 4
to know which filesystem is better for Maildir: ReiserFS, XFS or EXT3.
My conclusion was as follows:
- EXT3: reliable but very slow to read many small files.
- ReiserFS: best performance but unreliable and bad recovery tools.
- XFS: My choice, good performance and reliability.
I would contest the last two.
On CentOS 5.0, a had the same benchmarks and now, EXT3 and XFS seems to
had better or equivalent performance on Read and Create Random files.
One of this tests, using bonnie++, show this:
# bonnie++ -d /mnt/sdc1/testfile -s 8192 -m `hostname` -n
50:150000:5000:1000
bonnie++? Not appropriate. Try this:

And add JFS to the mix. You will be surprised.
What i want to know is: Anyone use or recommend EXT3 for Maildir?
If you do not have full blown battery back for write caches yes.
My configuration: 3Ware 9650SE-8LPML, 8 drives SATA2 ST3500630AS 500GB
on RAID 10.
Add BBU and XFS or JFS should do.
