[CentOS] OT:Which filesystem to use with large files

Hi all,

  Recently I have installed a centOS 5.4 server to use as a home NAS server. I need 
to use large files (8GB minimum) inside of it to serve via iSCSI services. Which 
filesystem do you recommends me to reach maximum performance: xfs, ext3, ext4, gfs2 
....??

Thanks.
