Among the issues I would check:
* Are any of your hard drives approaching full?
No.
* Do logs or utilities like smartctl show any disk errors?

* Have you recently upgraded any major packages?
This OS was installed last week. I think there might be somethings set
to auto upgrade, so it's possible something was doing that. The slow
response appears to have stopped.
* Is your machine running hot?
No.

I'm vaguely concerned about the 639MB of swapped used. That number
sits for me somewhere between comfortable and uncomfortable. If you
reboot your machine, I'd suggest keeping an eye on your swap-used
number. Perhaps it's fine, but it's just high enough to warrant a
notice.
Before restarting, swap-used was 639 (or so). After restarting it is 0.
