When I migrated to RAID6 a couple of years ago, I tested xfs, jfs, ext3/4, and in my application, xfs was the performance winner, followed closely by jfs. ext3/4 had a relatively poor showing -- your mileage may vary, of course; the majority of our backups are Windows systems using an rsync client. (I'm afraid I'm traveling, so I haven't got more concrete numbers handy, though I did report them on this list at the time.) My tests were done on a 6TB RAID6 array, with 2G RAM (the system has subsequently been upgraded to 8G; it runs a 32-bit kernel with PAE.) ------------------------------------------------------------------------------ LogMeIn Central: Instant, anywhere, Remote PC access and management.
