With the bios update, it takes longer to trigger, but eventually, yes,
the system slows down. Videos get out of sync, opening applications,
moving windows, menus all get really slow.

~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

In an attempt to quantify, I run hdparm and gtkperf. They both show
large losses in performance.

Before:
~$ gtkperf -a
Total time: 12.02

~$ sudo hdparm -tT /dev/sda
 Timing cached reads:   1674 MB in  2.00 seconds = 837.49 MB/sec
 Timing buffered disk reads:  64 MB in  3.11 seconds =  20.57 MB/sec

After:
~$ gtkperf -a
Total time: 40.88

~$ sudo hdparm -tT /dev/sda
 Timing cached reads:   442 MB in  2.00 seconds = 221.04 MB/sec
 Timing buffered disk reads:  62 MB in  3.05 seconds =  20.31 MB/sec

Bug description:
  A while after logging on, the system gets really slow. Menus and
  window movements take a while to respond, switching windows is slow,
  etc.

  This is a regression, it was not like this using Ubuntu 12.10, it just
  started on 13.04. Tried different desktops (Unity, GnomeFaillback,
  Lxde). They all have the same issue.

  Testing showed the issue is triggered by the TLP power management package.
  TLP was installed in an attempt to resolve issue of fan running constantly.
