Sorry to chime in; I had wanted to bring this to Brian's
attention a few days ago, but always got side-tracked:
Here are results on my IBM/Lenowo X41 notebook
model name : Intel(R) Pentium(R) M processor 1.50GHz
cpu MHz : 600.000
bogomips : 1198.37
MemTotal: 1546600 kB
with *no* graphics acceleration:
Everything is local but not really fast hardware

which is somewhat dramatic,
and for tk*() pseudo-animations, I have definitely needed to use
type = "Xlib"
