What image and what VM are you using?!

Are there any particular places where you feel it?!

We can only speed up things if we know *what* is slow. Tallies would help.
Descriptions of operations that are slow would help. Basically *everything*
that goes beyound simply complaining would help ;-) But one thing you should
certainly check is if Squeak's display depth is set to that of your OS
display. In particular with the 3.0 image (defaults to 16bit) you may feel a
heavy penalty for running in 8bit OS depth.
