CentOS - Apr 2007 - 3ware cards and new firmware in 9.4.1 codeset

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.

That is idiotic.  I guess I won't be upgrading my firmware.  Screwups 
like this really risk their strong following among Linux users.

There is NO WAY I'd use an unsupported file system on a production box.

Cheers,

so they boost MS file systems against Linux file systems?  Are they nuts?

My "Foundation" verse:
Isa 54:17  No weapon that is formed against thee shall prosper; and 
every tongue that shall rise against thee in judgment thou shalt 
condemn. This is the heritage of the servants of the LORD, and their 
righteousness is of me, saith the LORD.

Wow, that's stupid.  I guess we'll be switching to Adaptec cards...

Thanks for the "head's up" on this.
