I just tried booting in rescue mode, opened a shell as root and copied the same ISO file to the USB stick with Midnight Commander, and it copied MUCH faster - averaging 5.6 MB/sec.
I then tried booting normally, but at GDM screen switched to a text vty, and repeated the copy with MC again. Still good, about 5.5 MB/sec. I then tried logging into Gnome, opening a terminal and copying the same file with MC again... it gets to about 25-30% complete, then just gets slower, and slower, and slower, eventually bottoming out at around 650 KB/sec. This looks like it's something related to whatever is running during a Gnome session. Maybe GVFS-related, but I doubt it, since I specifically mounted the USB stick manually as root from a bash prompt, and used MC to copy (which wouldn't be using GVFS). -- USB file transfers extremely slow and eventually cause kernel freezes https://bugs.launchpad.net/bugs/183839 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
