Package: hal Version: 0.4.7-3 Severity: normal
there is an option in /usr/share/hal/fdi/90defaultpolicy/storage-policy.fdi that sets the "sync" option for hotplugable devices. (when automounting with gvm) This seems to be a good idea to avoid loosing data when unplugging the device without unmounting.... BUT: when you set the sync mode on usb-storage devices (usb keys, etc.), you get a VERY POOR tranfer rate, often ten times slower than without the option! I once wrote a small script to benchmark usb keys transfer rate in sync mode with several block sizes. More information here: http://ccomb.free.fr/wiki/wakka.php?wiki=UsbStorageBenchmark I believe the sync mode should never be used except for debugging cases. This is like using the sync mode of X... not good for performance and not for real use. The problem is: if the device is mounted without sync, with the current behaviour of Gnome, the user is not warned during the real copy when unmounting, and there is some time lost while waiting for the copy. I think a correct behaviour should be: - hal/gvm should mount WITHOUT the sync mode - nautilus/gnome-vfs should either : - popup a window during the unmounting (just like kde), OR (better) - autoflush the data to the device after a few seconds, while showing the copy popup window. -- System Information: Debian Release: 3.1 APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.10-1-k7 Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Versions of packages hal depends on: ii adduser 3.63 Add and remove users and groups ii dbus-1 0.23.4-1 simple interprocess messaging syst ii dbus-glib-1 0.23.4-1 simple interprocess messaging syst ii libc6 2.3.2.ds1-20 GNU C Library: Shared libraries an ii libcap1 1:1.10-14 support for getting/setting POSIX. ii libexpat1 1.95.8-1 XML parsing C library - runtime li ii libglib2.0-0 2.6.4-1 The GLib library of C routines ii libhal-storage0 0.4.7-3 Hardware Abstraction Layer - share ii libhal0 0.4.7-3 Hardware Abstraction Layer - share ii libpopt0 1.7-5 lib for parsing cmdline parameters ii pciutils 1:2.1.11-15 Linux PCI Utilities ii udev 0.056-2 /dev/ management daemon ii usbutils 0.70-5 USB console utilities -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
