Thank you for the helpful advice. Actually I had searched around more than a little, and had studied the Oracle documentation. I was just seeking some practical advice, for which I thank the other posters.
I am going to go for the memory upgrade (assuming my laptop will support it), so as to improve the performance a bit.
However, the good news is that I am almost there, in advance of the memory upgrade:
