What's more, the Unix graphics subsystem for SheepShaver is almost the 
same as in Basilisk II. Noticeable difference is design 
(object-oriented in B2), and an extra ppc routine that is called 60 
times per second. I hoped that recent JIT rentrancy + little 
optimizations  would improve it but it didn't either.

That's why I definitely think it's not related to stuff in 
Unix/video_x.cpp. But I can be wrong. ;-)

Really, latest features and optimizations (NQD, reentrant JIT, use of 
DR emulator, etc.) were meant to attempt to speed up the problem you 
mention. Finder is also slow on my PBG4 in emulated mode, though 
graphics performance as reported by benchmarks looks good.
