I am moving away from using ext3 on my servers due to its high overhead and lower performance. I am considering either XFS or JFS.
Does anybody know how XFS compares to JFS or if they can be compared together. I want to use a journaled file-system on a IMAP server that holds 4000+ users mail. The IMAP volume is using RAID 5 ARRAY, but we do not have a generator. When the power goes out for over an hour, the server goes down hard. A journaled file-system, helps speed recovery from the power outages. Although this has not happened yet, I want to be prepared for it. Currently, the ext3 file-system seems to be slowing down mail accessibility under heavy loads. Additionally, I am using kernel quota on the file-system, which I hope to phase out with Courier IMAP maildrop in the near future. I am aware that XFS is one of the best performing journaled file-systems out there, but how does JFS compare to it. Has anyone seen any tests ran side by side The only reason I ask is that the JFS file-system seems to have made it in the standard Debian Kernel (2.4.20). -Ted -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
