[B2-devel] SheepShaver performance

[Tomasz J. <to...@je...>]

Hello!

First of all I wanna say that SheepShaver is really a great piece of code. I
never imagined anyone would be willing/able to code a real PowerMac
emulator. Nonetheles, I have little performance problems with it.
On my Duron 1.3 it is pretty slow, but generally usable. However, sometimes
the emulator freezes for a few seconds. Host CPU consumption is still 100%,
but you can't do anything (within emulator, that is).
There are also some problems with mouse input (probably for the same reason)
- sometimes you need to click several times before a button is pressed down
or a folder opened.
It looks as if the mouse input thread (provided SheepShaver is written in
multithreaded manner) was starved by CPU emulation thread ot JIT thread... I
think so, because Basilisk II was multithreaded in Windows and you could
play with thread priorities with good results.
