[Newbies] Why Squeak is so sloooow?

Well. I have tested in other PCs with 3.8.
With this centrino 1.8Ghz, this evening I have tested
with 3.8, 3.9 and 3.7. (not croquet)
I'm not speaking about calculate power of squeak (that
I know is very good), is only a graphical question, in
sum up, to move pixels from here and there...
Results:
In three versions I find slowdown when I load some
blobs and one bouncingAthoms. Actually, bouncingAthoms
is what I take as a reference, because you can see
easily if "athoms" goes faster or slower.
BUT there are some diferences between versions.
3.7 run very fast, but the work of the CPU increase
quickly even shaking the mouse from left to right.
In 3.8 I find slowdown specially when move windows.
3.9.7 in my case is the best election. Mouse shakeing
waste ZERO cpu, and shaking windows too. But, if move
other graphics objets the cpu increase quickly, for
example, a Tetris window. I have notice that if you
load the Tetris game and keep press the down key for
changing a position of a tetris piece constantly,
wastes the half of my CPU. In some games, over all, in
arcade games, you need sprites changing contantly, I
supouse that it would be a real load for squeak.
