You -might- want to enable HT (hyper threading) in the machine's BIOS,
and test the performance.
Some applications get a nice 10-15% boost by enabling Hyper Threading.

By the looks of it, your machine is almost idle.
What it is used for?

Either way, switching to x86_64 should improve the performance somewhat.
(x86_64 doesn't require high-memory support - which should reduce the
over-head somewhat)

1GB is more then enough (given the memory usage)
