Yet Another Slow Copying Issue Thread
I'm having the same problem copying a fresh sparse image over to a 1TB WDD MyBook Studio. I realize that people are having troubles with this particular line of disk, but before I upgraded to Leopard SD! was performing backups in less than 30 minutes and I haven't had any issues with the drive at all. Now its taking nearly double that. I'm experiencing copy rates of 9 mb/s all the way up to sometimes 22 mb/s whereas on Tiger it was much faster than this.
Any ideas as to what the problem may be? I put the backup folder on my external in spotlight's privacy list and that didn't speed it up any. Thanks! [edit] An observation: the backup I just performed seemed to start out fast and gradually degrade as it moved from folder to folder. It started out at 22 mb/s when copying my users folder, but by the time it hit the Library and System folders it was down to 9mb/s. It just started on the Applications folder and its down to 8.5 mb/s. Interesting. Here's a section of the log: | 05:10:43 PM | Info | / | 05:10:46 PM | Info | /cores | 05:10:46 PM | Info | /Network | 05:10:46 PM | Info | /.vol | 05:10:46 PM | Info | Ignoring /.vol | 05:10:46 PM | Info | /.Trashes | 05:10:46 PM | Info | /bin | 05:10:46 PM | Info | Ignoring /.hotfiles.btree | 05:10:46 PM | Info | /.Spotlight-V100 | 05:10:46 PM | Info | Preserving /.Spotlight-V100 | 05:10:46 PM | Info | /Users | 05:21:17 PM | Info | /Developer | 05:29:58 PM | Info | /Library | 05:43:34 PM | Info | /sbin | 05:43:34 PM | Info | /usr | 05:46:40 PM | Info | /System | 06:02:05 PM | Info | /private | 06:02:05 PM | Info | Ignoring /private/var/vm/sleepimage | 06:02:12 PM | Info | Ignoring /private/var/vm/swapfile0 | 06:02:23 PM | Info | Ignoring /private/var/db/BootCache.playlist | 06:02:23 PM | Info | Ignoring /private/var/db/volinfo.database | 06:02:23 PM | Info | Ignoring /private/var/run/syslog.pid | 06:02:23 PM | Info | Ignoring /private/var/run/configd.pid | 06:02:23 PM | Info | Ignoring /private/var/run/DirectoryService.pid | 06:02:23 PM | Info | Ignoring /private/var/run/pcscd.pub | 06:02:23 PM | Info | Ignoring /private/var/run/com.apple.blued.launchd | 06:02:23 PM | Info | Ignoring /private/var/run/diskarbitrationd.pid | 06:02:23 PM | Info | Ignoring /private/var/run/ntpd.pid | 06:02:23 PM | Info | Ignoring /private/var/run/mds.pid | 06:02:23 PM | Info | Ignoring /private/var/run/automount.initialized | 06:02:23 PM | Info | Ignoring /private/var/run/appfwd.pid | 06:02:23 PM | Info | Ignoring /private/var/run/resolv.conf | 06:02:23 PM | Info | Ignoring /private/var/run/mach.sym | 06:02:23 PM | Info | Ignoring /private/var/run/mds | 06:02:23 PM | Info | Ignoring /private/var/run/smb.conf | 06:02:23 PM | Info | Ignoring /private/var/run/nmbd.pid | 06:02:23 PM | Info | Ignoring /private/var/run/hdiejectd.pid | 06:02:23 PM | Info | Ignoring /private/var/run/utmpx | 06:02:23 PM | Info | Ignoring /private/var/tmp/com.apple.speech.synthesis.globals | 06:02:23 PM | Info | Ignoring /private/var/tmp/launchd | 06:02:23 PM | Info | Ignoring /private/var/tmp/com.WD.WDDriveManagerService | 06:02:23 PM | Info | Ignoring /private/var/tmp/mds | 06:02:26 PM | Info | Ignoring /private/tmp/launchd-120.K2Ktvy | 06:02:26 PM | Info | Ignoring /private/tmp/launch-wsw2iO | 06:02:26 PM | Info | Ignoring /private/tmp/launch-c5zWZS | 06:02:26 PM | Info | Ignoring /private/tmp/launch-K5kI5P | 06:02:26 PM | Info | Ignoring /private/tmp/SDTargetImageDevice | 06:02:26 PM | Info | Ignoring /private/tmp/target.indexState | 06:02:26 PM | Info | /Applications | 06:09:12 PM | Info | /dev | 06:09:12 PM | Info | /.fseventsd | 06:09:12 PM | Info | Preserving /.fseventsd | 06:09:12 PM | Info | /net | 06:09:12 PM | Info | /home | 06:09:12 PM | Info | /Volumes | 06:09:12 PM | Info | Ignoring /Volumes/Masamune | 06:09:12 PM | Info | Ignoring /Volumes/Saya | 06:09:12 PM | Info | Ignoring /Volumes/MEDIAVAULT | 06:09:12 PM | Info | Ignoring /Volumes/MasamuneLeopardBackup | 06:09:12 PM | Info | Evaluated 697998 items occupying 30.65 GB (125694 directories, 549801 files, 22503 symlinks) | 06:09:12 PM | Info | Copied 697876 items totaling 28.41 GB (125675 directories, 549699 files, 22502 symlinks) | 06:09:12 PM | Info | Cloned 28.41 GB of data in 3509 seconds at an effective transfer rate of 8.29 MB/s [/edit] Last edited by jduv; 02-08-2008 at 06:10 PM. |
