Title:
  Extremely poor system performance during large file operations

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Running Intrepid Ibex 8.10 64-bit, I get extremely poor system
  performance whenever a large file operations are taking place.
  Examples are copying multiple gigs of files, moving multiple gigs of
  files, or unzipping very large archives.  Firefox becomes unresponsive
  and/or dims every other minute, the package manager takes 3-4 times as
  long to install a new package, and so forth.  I'm using Nautilus to
  copy the files, but I believe I tried a simple 'cp' in the terminal
  with similar results.

  I have a pretty beefy system (C2D, 4 gigs of RAM, hard drive with 32mb
  cache) and this problem doesn't occur in Vista, so I'm stumped.

  System monitor looks pretty normal even while usability is going into
  the toilet.  Not much RAM or CPU used, no significant paging going on.
