Hi David,

Here are the result of bonnie++, I'm not an expert to rellay understand 
if the results are good or bad, and if you have an advice, don't 
hesitate to reply.

- command line used (connection on server with ssh and putty) : bonnie++ 
-d /home -u root >result
- I use ext3 file system on all my partitions, and quota and acl. BUT i 
didn't activate quota and acl actually.

 Why ext3? because I know this file system is secure, and I use it since 
I use Linux. I heard that reiserfs is faster, but a little bit less safe 
than ext3, in special
condition. My first objective is data integrity, performance come after. 
But I'm open to
