Thank you for the link to that report, Nevile.  While I have been a 
subscriber to it I also follow many reports, so your link is very helpful.

I was eager to run the test stack there, but discovered there isn't one. 
  I don't mind creating one, but it would be helpful to know what's 

Have you seen any difference between a stack with little content but a 
large number of objects vs one with a small number of objects but a lot 
of text or images?

Once I can reproduce the test, I'll modify it to isolate the time 
devoted to stack files separately from other file I/O for 
equivalently-sized files.
