BTW it seems like you have connected your USB stick to a USB 1.1 port, so that could certainly explain why performance might not be as expected. It would still be useful to get the dstat trace as mentioned before.
You can tell by a look at the output of just a simple lsusb that shows the flash disk is on a bus with a 1.1 root hub. Or, looking at your dmesg that says "new full speed USB device" you would know since full speed translates to 1.1, where as high speed translates to 2.0. -- [jaunty] usb file transfer is very very slow https://bugs.launchpad.net/bugs/334914 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
