A load average of 2 isn't bad.
Depending on how many windows you have open and what they are, that could possibly account for the load average.
I have a C200 with 512MB RAM and a single 200 MHz processor running 11i (32 bit). It currently has a load average similar to yours.
# uptime
9:31am up 4 days, 23:26, 12 users, load average: 3.34, 2.85, 2.58
It is running OK and I don't have any problems. I really wouldn't be too concerned with the load average you are seeing.
