--- Comment #3 from Arjen Hiemstra <ahiems...@heimr.nl> ---
The charts used by System Monitor use GPU based rendering, which means that
LLVMpipe needs to emulate all the shader logic normally done by a GPU. This is
pretty heavy for most CPUs, so you end up with a lot of CPU usage. There is not
a whole lot we can do about that, as can be seen in the hotspot screenshot most
of the time is taken by the LLVMpipe rasterizer.
