Below is another interesting msg from a recent LKML about 
the interactive peformance of 2.4.17-pre2.

  Something beautiful has happened in 2.4.17-pre2.
  
  Interactive Latency during very heavy disk I/O has dropped dramatically.
  Several LTP tests have a tendency to make interactive performance poor.  
  The improvement in 2.4.17-pre2 is astonishing.
  
  Normally runalltests.sh does one test at a time. Since the usual 
  interactivity slowdown during the growfiles tests didn't happen, I 
  tried running a bunch of things at once.  
  
  Concurrently:
  3 growfiles scripts (run all growfiles tests in LTP).
  3 LTP runalltests.sh
  setiathome
  make clean dep bzImage modules 
  list directories with lots files that hadn't been listed before in this boot.
  ps, w, logout, login.
  3 irc clients, play a couple mp3s, read entertaining Coding Standards thread.
  
  The start time of the concurrent growfiles and runalltests.sh was spaced 
  out, so different tests were being executed.  
  
  Occasionally ls or w had a 10 second or so delay, but delays were infrequent, 
  and shorter than usual.
  
  Kudos to all the Kernel Hackers!
