The System Monitor application is great - except that the Resources tab is a real pig. It uses a lot of CPU to do its thing - I have a quad xeon system and it uses up to 40% of one of the cores just for graphing!

That's not such a big deal for this system, but on a single core older system it could really bog things down when you're trying to see what's going on with performance.

Also, we sort of have a quantum effect where the observation affects what you are trying to observe. Not so great.

I propose trimming out whatever fancy stuff is making it slow, be it spline interpolation for the graphs, or whatever. Just scale back to drawing some plain old lines until the smooth graphing stuff is working as fast. I'd rather see plain lines than have the performance monitor be inaccurate.
