I'm looking forward to your feedback.
Well, not really much feedback, I just played with the demo
programs. I'm really impressed how well everything is already.
Great job!
I don't have wayland here, but this sounds super impressive.
Way to go Manolo, you're amazing!
Conclusion:
Using Cairo doesn't seem to be that slow in conjunction with
Wayland which uses (AFAICT) memory mapped buffers for
communication (rather than sockets or network connections like X11
does). How does "local X11" communicate? Anybody?
Pretty sure X11 when used locally now uses IPC + shared memory
when running locally,
unix domain sockets instead of the overhead of TCP/networking.
I have a vague memory that Silicon Graphics donated some code to
X11 to improve the speed
of rendering under X11, but I can't remember if it was specific
to OpenGL (GLX), or included X11
as a whole (Xsgi).
MIT was behind a lot of improvements too, I don't remember the
history very well.
There may be more details burried in here:
