Oh yeah there are lots of tips and tricks for optimizing performance.
Some standard stuff to check:

* Any processes gobbling cpu, memory, or disk IO?  (top, ps, nmon, atop, free -m, nice/ionice, etc.)
* Got any unusual cron jobs set up?
* Is it swapping to disk?  (top or vmstat should show this, or the %wa number in top)
* Can you repro it in a guest session?
* Can you repro it on a Live CD?
* Any firmware updates for your motherboard?

dmesg is a good thing to check; especially keep an eye on that GPU lock
message.  If you're able to correlate that to when the sluggishness
happens that would be quite interesting.  If the message is there when
the system is working fine, that would reinforce my guess that the bugs
are separate.

Hardware's also a possibility.  Switching to a SSD helped a ton with
performance just in general, and particularly with swapping.  Increasing
ram can help in some situations.  On laptops a failing power supply can
cause weird bugs (esp. if it's fine when on battery).

Good luck, let me know what you find.
