Yes, it makes sense that hz for hz, the SPARC Self system outperforms the Mac: it has optimizing compiler.

To minimize morph sluggishness, try to limit the number of open outliners you keep around on your screen. When you drag a morph across an outliner in the background, the background morph does a lot of work to repaint-no bits are cached. I heard a rumor that the Squeak morphic system does do the bitmap caching. Self's does not because Randy wanted to be able to have animated morphs in the background.

Hi

I have been following this discussion on Self performance on the Mac with some interest. I also first found the performance on my G3 somewhat slow (400MHz G3, 256MB RAM), but that was after having used Self on a 400MHZ UltraSPARC, with ~512MB of RAM. Perhaps people are comparing the two. I do find that the graphics performance (ie dragging Morphs around) somewhat more sluggish than on the SPARC, but considering what Self is doing just to give that sort of performance in Morphic makes it clear that Self is not slow. To put things into perspective, try running Morphic in a commercial type Smalltalk, and see what that performance is like (baaad). I have to admit though that Squeak, is not sluggish on a 400MHz Mac.
