I get a different result: the comparison I sent initially among ordered/journal/writeback was done on a _SCSI_ drive. Building with bogofilter from randlist.txt with data=journal takes my laptop/IDE 27 minutes and my tower/SCSI 26 and a half. So I would be inclined to doubt that the solution may reside in anything IDE-related. On my laptop, simbf takes 8m 14s (ext3, data=ordered). On the SCSI drive mentioned above, with ext3, data=writeback, 18 seconds flat. With ext3, data=journal, it was 3/4 done when I executed while true; do kill -9 (simbf process); done -- the only way -- at ten minutes; it had completely locked up access to the drive and wasn't interested in ctrl-C. With ext3, data=ordered, simbf completed in 7 minutes and 8 seconds. With ext2, 13.7 seconds. Again, this was a SCSI drive. Sorry I didn't get to this last night. -- | G r e g L o u i s | gpg public key: | | http://www.bgl.nu/~glouis | finger greg@bgl.nu | | Help free our mailboxes.
