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

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.
Thanks, Aleksandr
What version of Squeak are you using? I found the DejaVu fonts made the GUI unusably slow using 3.8 - I haven't tried them in 3.9, and I don't know if this problem has been resolved. But out of the box both 3.8 and 3.9 are very fast, and I get nowhere near 100% CPU load.

note that there is one patch missing in 3.9 for font caching.

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.

This would be interesting to profile - we can have gross inefficiencies in how the tree widget operates and/or how the SM model behaves when asked about labels etc. I can see if I can get time to do that.
Can you give me a description of your image so that I can replicate it? Or can you put it up for me to use? If you can I can give you an ftp area to put it.
