Subject: Re: Why is my system slowing down?
Cpu(s): 75.7% us, 2.3% sy, 0.0% ni, 0.0% id, 21.6% wa, 0.3% hi, 0.0%

It shows you at 75% of the CPU being used by User processes. Is this normal?
Do you consistently see this much usage on the top? If so, it would explain
the slow down. You probably have a rogue process somewhere chewing up your
cpu cycles. Your space is starting to get a bit low 2g is plenty enough
though to no cause the problem you are describing; I don't think. But CPU
usage would definitely slog your system down.

What are your top 3 processes in top?
