The important issue is to determine what your applications are doing with files. The most heavily loaded systems I run at the moment are mail servers. They typically have writes outnumbering reads by a factor of about 9:1. The majority of email is never read from disk, it's either read by the user and deleted while it's still in the cache, copied to an offline-IMAP system while it's still in the cache, or automatically deleted from the spam folder before the user notices that it's there. For such use the way BTRFS defragments writes and fragments reads is a feature not a bug! -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
