This was a fresh install, not an upgrade. I have applied all updates made available since the installation, but performance has not changed.

I have not installed any other linux on this laptop. For comparison purposes, I booted it from a 17.04 (Artful) live USB, which has kernel 4.13.0-16. It doesn't feel faster, but of course there are many factors involved ... When running Artful, /proc/cpuinfo displays "cpu MHz : 2000.000" for all 8 CPU's, and never varies. When running c-ray, all 8 CPUs are 50%--75% used, but the fans never spin up. "cpupower frequency-info" reports "current CPU frequency: 400 MHz (asserted by call to kernel)", which contradicts /proc/cpuinfo.

I will try an upstream kernel tomorrow.
