It's nice to know that there is a way of speeding up the 3.0 GUI 
by increasing the number of buffers, and baring any better solution,
that is what I will do when my cdrom/3.0 upgrade arrives in late December.

But is that the root of the problem? Namely, that the number of buffers 
initially alocated by 3.0 is less than the number alocated by 2.x?  
If so, then it's a simple bug to fix.  

There could be other explainations.  From reading complaints on the net,
my best guesses are that the problem arises from one of the following:
1. Workspace Manager might be much larger in 3.0 than 2.x, and require more
   real memory when moving windows around, etc.  On my 2.1 machine 
   Workspace Manager asks for about 20 mb of (mostly virtual) memory.
2. Workspace Manager is slower because of a new feature, like distributed
   objects.
3. Workspace Manager has a bug.
4. NeXT also has added compressed paging and/or swapping.  Maybe the 
   memory management is slower in 3.0 than in 2.x, due to a bug or
   the implementation of compression. 

I also noticed a number of people claiming that the two pre-release
versions of 3.0 had snappier window management than the final 
public version.  This makes the problem sound like a bug fix that 
in turn generated a new bug!
