Our definitions of "deadly slow" may be different. I run Squeak on an old iBook...
Machine Name: iBook G4 Machine Model: PowerBook6,5 CPU Type: PowerPC G4 (1.1) Number Of CPUs: 1 CPU Speed: 1.33 GHz L2 Cache (per CPU): 512 KB Memory: 768 MB Bus Speed: 133 MHz
...with less memory than you have and find it more than fast enough. What are you doing with Squeak?

Well we have almost identical iBooks (I have 256 MB more and an updated CPU):
Machine Name: iBook G4 Machine Model: PowerBook6,7 CPU Type: PowerPC G4 (1.2) Number Of CPUs: 1 CPU Speed: 1.33 GHz L2 Cache (per CPU): 512 KB Memory: 1 GB Bus Speed: 133 MHz
But I can not say it is more than fast enough. It might be that I was a bit incorrect in my previous message, and I needed to title it "Squeak CPU speed". But the sad story that I do almost nothing with it, I'm just trying to use it figure out what it is. And I see that GUI responsiveness is too low and the such basic operations as changing a window size or moving it (with fastDragWindowForMorphic disaibled) load CPU upto 100%. And after I've installed DejaVu fonts, I need to wait upto 4 seconds everytime I change size of the SqueakMap Package Loader window. Switching from the Class libraries category to Development tools takes about 8 seconds.
So...how does a vanilla image perform? And which image version are you using? I have fastDrag enabled (disabling is too slow for me too) and I haven't installed those fonts.
