Phoronix: Intel P-State Driver Might Still Be Causing Wonky Linux Performance
Last year on earlier versions of the Linux kernel we've uncovered performance issues around Intel's P-State / CPUfreq driver that was causing adverse performance in certain configurations. While it looked like most of the Intel CPU clocking issues were resolved in more recent versions of the Linux kernel, it looks like some Linux performance problems are present in Linux 3.14...
