[Bug 1208993] Re: Ubuntu slows down and hangs while copying file from/to USB

 

Tried that a while ago, it made working with already open applications
and playing music OK (it stopped stuttering while copying), but if I
copy something large and want, for example, to start a terminal window,
I can click on terminal icon, but the window won't be shown until
copying is finished. I mean, how much disk activity is needed for
opening terminal window?

I have 3 harddisks in my machine. Let's say that OS is on HD1. The same
problem with starting terminal occurs even if I start copying from HD2
to HD3, so I guess it has nothing to do with HD speed and/or caching.

And this is not only Nautilus problem (at least for me). Same thing
happens if I copy/unpack from command line, or Double Commander
(unpackig large archives does the same thing). Generally, every time
some process has a lot of work with hard drive (it doesn't need to be an
USB HD, that makes things just more sluggish), my computer is noticeably
less usable until HD work is finished. I think that something is wrong
with the way I/O operations are scheduled, as some processes can take
all the machine's disk I/O resources for themselves, leaving absolutely
nothing for others.

Title:
  Ubuntu slows down and hangs while copying file from/to USB

Status in nautilus package in Ubuntu:
  Confirmed

Bug description:
  Hi

  While copying many and large files to and from a USB drive, the system
  becomes incredibly slow and sometimes hangs. I watched the system
  monitor while it was running slowly but cpu was not above 50% at any
  time, the same for memory.

  I'm using the "WD my passport" HD with a USB3 port of my "ASUS K55VD"
  laptop.

  Description:	Ubuntu 13.04
  Release:	13.04

  nautilus:
    Installed: 1:3.6.3-0ubuntu16
    Candidate: 1:3.6.3-0ubuntu16
    Version table:
   *** 1:3.6.3-0ubuntu16 0
          500 http://ubuntu-archive.mirror.nucleus.be/ raring/main amd64 Packages
          100 /var/lib/dpkg/status

  
  Steps to reproduce:
  1) Aquire many large files (like your totally legit moviecollection)
  2) Copy files to external HD
  3) Open your browser and be sad when your system becomes incredibly slow after a few minutes


  This is my first bugreport so if I'm missing something, please tell
