Kernel-Based X11 Server Claims 2x Performance Over X.Org

[Auzy]

A Xserver in the kernel? Doesn't that mean that the kernel panics when the Xserver crashes?

Definitely sounds like it is a step backwards for everything except performance. Also, f you upgrade your kernel, there is probably more likelihood that the Xserver will need a recompiled/to be patched to work again.

In contrast, on Windows with Nvidia (and maybe other drivers), and possibly Wayland, if the graphics driver crashes, it may be possible to recover automatically without a reboot / work-loss.

Technically, its easier to get better performance probably out of anything by sticking it into the kernel, but, with a good design, you could probably obtain similar performance from user-land anyway (along with better security).

So, um, benchmarks?

Phoronix: Kernel-Based X11 Server Claims 2x Performance Over X.Org

MicroXwin is an X.Org Server alternative for an X Windows System implementation for Unix/Linux desktop. The developers behind MicroXwin are claiming that by implementing their X Server in the kernel they are getting a 2x performance advantage while using less memory and being binary compatible with Xlib...

I'm sure we'll hear about all the downsides of such a thing in this thread. But for a hard core gamer, an X server that provides this much of a performance win would be worth it.

So kernel developers rant about how difficult is maintain the code due its complexity and here it goes one pal that adds a lot more code.

And what code ...

Even if it's leaner, it stands X, with all that complex architecture and stuff.

Now in kernel ...


Maybe would be usefull in embeded systems. But for desktop and servers ... well.
