Intel P-State Driver Might Still Be Causing Wonky Linux Performance
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...
On Ethernet too
I see a _major_ performance regression on 3.14 Ethernet performance as well, this issue might explain that.
On 3.13 I can easily saturate my 1Gbps link, on 3.14 it's 100 (!!!) times slower, I only get like 1.2MBps
This is on my T440s with F20.
I run 3.13 now obviously
How do you like the T440s? Was thinking of getting one

But I have yet to hear that they've changed their mind about killing off support for 16-bit segments on 64-bit kernels.

You never got a W3.11 license? Even though I've long lost the box, floppies, and license, since I paid for one I feel fully morally ok to pirate w3.11 for a VM.
In between the original IBM PC which I, sadly, no longer have and the HP Pavilion 8160 (which came with Win95), all of our PCs were my father's bring-home-from-work laptops.
