We have many users who have large numbers of files per directory, and not having to search these in userspace when we get a stat cache miss is helpful. Just running a generic "netbench" test won't show any difference, as that test uses separate directories for each client with small numbers of files per directory. There's a reason I wrote this HOWTO (having to use an alternate link as samba.org seems to be down right now): http://man.chinaunix.net/newsoft/samba/docs/man/Samba-HOWTO-Collection/largefile.html Jeremy. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
