I've did some test and I managed to narrow this bug somehow. My setup: Macbook 2,1; Intel USB controller; Ubuntu 9.10 64-bit. 1st try: Patriot Xporter 4GB flash drive - no problems. 2nd try: Patriot Xporter 16GB drive - slows down when writing to USB drive under Gnome. It worked fine when I booted to recovery mode (pure CLI, no Gnome), mounted the drive manually and copied over 700MB of data. It slowed down in Gnome, both with automounting, and with manual mounting (though this time I can't guarantee that Gnome wasn't involved in that because I just remounted the drive manually after the Gnome's autodetection). So it seems that some subsystem invoked by Gnome (hal? udev? gvfs?) is responsible for the slowdown. Please tell me if this is relevant to this bug or should I file a new one?
I'm attaching the output of dstat ran while copying in Gnome. ** Attachment added: "dstat-sdb1-gnome-automount-try1.txt" http://launchpadlibrarian.net/36999761/dstat-sdb1-gnome-automount-try1.txt -- file transfers on USB flash key (pendrive) are slowing down with time https://bugs.launchpad.net/bugs/197762 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
