Did the CPU throttling stuff somehow get broken when you updated to
gcc-6.4.0? After updating a bunch of stuff a month or two back, I
noticed that builds suddently took 4X as long. I finally realized
that I had broken the CPU throttling feature and my laptop was always
running at 400MHz and not ramping up to 2.<whatever> GHz when doing
things like compiling large packages.
