I had noticed a certain sluggishness recently too but nothing as severe
as you have seen. This morning however, a new kernel appeared (I'm on
Proposed) to upgrade it to 3.2.0-29 & after applying that, everything is
much more responsive & the load averages have improved dramatically
(from around 0.85 to about 0.02 when idle). There was nothing else in
the upgrade apart from the kernel. I should also point out that I'm
using for Precise an old HP dc7600 with 2 GB's of RAM i686 running a
fairly full load: Apache, MySQL, Postgres, Mongo, Redis, NFS server as
well as all the usual Desktop clutter so it's hardly cutting edge
technology I'm using.

Maybe check your hardware (RAM, HD, etc). From what you're describing
there may be something amiss somewhere as it don't sound too good.

Cheers,

  Phil...
