I'm running the 2.6.3-full patch on my workstation now. No tuning applied at all. I reniced the X server to -10. When I have two kernel compiles (without any -j*) running there is a visible (=not really slow, but long enough to notice something) delay in responses while typing something in a xterm. In sylpheed there is the same issue. The standard scheduler didn't show this that extreme with only two compiles. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
