Some R3 based servers, (like the ones we currently ship on Ultrix,
and the R4 based servers we'll ship in the not too distant future),
already have the window manipulation speedups; in fact, the work
we did was given to MIT and accounts for much of the improvement in R4
in this area.  In the general case, the recommendation to use an
R4 server is a good one.

Other things which slow some people's implementations are slow
malloc's, which the server and toolkits use heavily, and if you are
paging significantly, you can just plain lose...  The memory savings
of R4 and some malloc versions can help greatly; the toolkits in
general need some serious dieting on memory usage.
