Re: [News] OpenOffice.org Gets a Lot Faster in Next Version

After takin' a swig o' grog, Erik Funkenbusch belched out
  this bit o' wisdom:

Well, Erik, could it be <cough> <cough> the fault of the /operating system/?

   The following table summarises the measured values on OpenOffice.org
   Writer cold start up. Cold start means that OpenOffice.org was started
   after a reboot and removing the prefetch file which created by Windows
   XP. For more details about the prefetch feature of Windows XP you can
   links at the end of this blog.

   Aspect         Time     Percentage

   Writer startup 24800ms  100,00%

   . . .

   It's obvious that file I/O plays the most important role on start up.
   More than 80% of the time needed for start up is lost due to reading
   libraries or data. Reading data files is about half the time
   OpenOffice.org needs to read all necessary libraries. It's also clear
   that raw CPU power doesn't help for a quicker start up.

Gotta love that good ol' XP I/O.

Being owned by someone used to be called slavery -- now it's called commitment.
