I just saw the following in the release notes for the new firmware for the later 3ware cards; Improved CIFS performance The firmware has been tuned to greatly increase performance with CIFS (Common Internet File System) protocol. However, this has resulted in performance with the Linux ext3 file system that is slower than earlier releases. We recommend that you use other Linux file systems, such as XFS. So it looks like ext3 performance would be worse. What are they thinking? They are going to drive linux people away. -- MailScanner is like deodorant...
