So, the question: How in WINE is implemented BitBlt function in order
to have so high performance and so low CPU load?
We use the X render extension. See dlls/winex11.drv/xrender.c.
(I am not an expert on the GDI parts of Wine, so no guarantee for
correctness of this information. I haven't followed the full path from gdi's BitBlt to the final X11 call)
Perhaps using XSHM for such things would be better (at least when the X server is local, which is almost always the case).

I never heard about XSHM, but it sounds really interesting. Unfortunately Google gives some very sketchy references about it. Is there more informative documentation about XSHM?
