The more ram the merrier. If you are thinking of running X and a web
server at
the same time (gasp), upgrade to more ram.

Having a swap file, of any size, will not slow down your machine. Not
having one,
and running out of memory will mean a crash.

So go for the 512 MB, and add a swap file for those 'just in case' times
...

You can always start with a 150 to 250 MB swap file and then watch the
box to 
make sure you don't need more. If you do run out of ram and start to
swap, things 
a r e  g o i n g  t o  s l o o o w  d o w n . . . . . but at least it
won't crash.

Expect the amount of 'free ram' displayed to dwindle down towards zero
at times.
It doesn't necessarily mean that you don't have any ram available, the
kernel just
hates to see any extra go to waste. It will be used for buffers/disk
cache and be
returned to use as soon as the box has something better to do with it...

Yes, this means more ram than you 'need' can speed things up since you
don't need
to load something from disk if it is already in ram.

512MB is a pretty large chunk of ram unless you are running a LARGE
load.

YMMV
