Re: USB: KDE faster than GNOME faster than TERMINAL ??!!

it is already mouted with sync, see the fstab line:
/dev/scsi/host0/bus0/target0/lun0/part1 /mnt/IntelligentStick auto sync,user,noauto,rw,iocharset=utf8 0 0

When KDE has finished copying the file, unmounting can be done with no delay. The file is really copied.

I believe the problem is to do with synchronos  writing to the device. It
probably means that KDE is reporting the time for the drive to report that
it has copied files. Try adding sync to the fstab, and then see what

Something very strange :

I have done a test with a small USB1 memory key (i-stick).

I copy a 1.9 MB file from the hard drive to the USB mass storage
device, with three different methods:

1) from KDE with Konqueror : 7s  (~280 ko/s)
2) from Gnome with Nautilus: 30s (~60 ko/s)
3) from the console with cp: 50s (~40 ko/s)

The correct speed is done when using KDE, the other two are very very
slow. Does anybody has already seen this ???

Its to do with blocksize. Try 'time dd if=1.9_file of=/usbhdd/out
obs=xxxx' Vary xxxx over 2**n : 8 <= n <= 16. On my usb key ~3000 was
optimum. YMMV. Unforunatly vfat(at least my version) doesn't support
blocksize as an option.
