Size of Swapspace

Leave it. There is no reason to enlarge your swap unless you need it and
if you quadruple your memory you are probably going to need swap less.
Every system I have regardless of RAM amount currently has 2 GB swap
(unless they're really small systems, and then they have less) but the
system will try to avoid using swap in most cases unless RAM is filled up
because swap is ssslllllloooooooooooooooowwwww. If you are actively using
two gigabytes of swap because your memory is completely filled you will
wish you were dead anyway; increase that to eight gigabytes and you'll
just wish you were dead four times. :-)

Good luck.
