      I don't know what you did in the Java Performance
      Pack for Windows (JPP113.exe) but File/Disk IO
      is now really slow. Operations that took about
      1 sec now take 5-6 secs to complete.
      Other than that, it looks good. Looking
      forward for the next release.

      Hi,

      Well, the problem showed up mostly on a slower NT server machine
      running JDK 1.1.3 and the JPP. I used RandomAccessFiles
      and had many seeks, reads and writes (between two files).

      I tried to put together a test program for you to show
      the problem but I can no longer reproduce it. This is really strange
      as I had no problems a week ago (the code in that part of the program
      hasn't changed). I'm at a loss of what happened other than I guess I
      cried 'Wolf' before I should have. I'm sorry for wasting your time.
      I'll make sure to poke into a problem a bit more next time something
      like this comes up before informing you guys.

      Again, sorry for wasting your time, and thanks for looking into
      this (non-existing) bug.

      Darcy
