Bug Description
Binary package hint: nautilus
Fresh install of karmic beta 10 Oct 2009
USB transfers great (12-15 Mb/s) to a USB 2 stick, reads were 12-17 Mb/s
After a couple updates I noticed the transfer rates dropping (3-6 Mb/s; subsequently now the transfer rates are slowing down to 1.2 Mb/s
I have noticed slow transfers with Ubuntu for a little while. tried the karmic beta live CD, the best transfer rates I have seen in a while.
I even purchased a small powers USB 2 hub (possible voltage loss due to cable length affects transfer rates for testing with Jaunty (previously installed on 3rd HD. Legacy USB 1.1 still enabled, even with the LCD of Karmic running for 6 hours transfer rates were 12-15 Mb/s.
