Hi, i would to ask something about swap space:

i quote from the book "How Linux Works—What Every Super-User Should
Know"

"Reserve two to five times as much disk space as you have real memory
for swap. It doesn't make sense to go any lower, because you may
actually risk running out of memory. If you go higher and actually
intend to use all of this swap space, you will likely suffer serious
performance problems because the system will spend all of its time
swapping (a condition known as thrashing). "

i can't understand why if create a really big swap partition i will
have a performance decrease????It seems to me
that in the worst case scenario, i will be throwing disk space
[because the system will never use the swap partition if it doesn't
need it......why this would have a negative impact on the
system......]

I think a lot of documentation was written in the days of 8 megs of
memory. I remember being the envy of the computer club with 16megs. At
install I've just let Fedora set it up for me without asking.
