swap rules.

Hi managers.

What are the general rules for sizing swap on current systems?
As cheap as memory is getting these days the newer systems we are playing
with have 32 or 64GB ram.
Back in the day when memory was expensive, a 2:1 Swap partition size to
RAM ratio was pretty normal.
Then It was 1:1 as memory has gotten cheaper.
Is it still a good practice to do 1:1 to allow for huge core dumps on a
crash?
Or is 1:1 Swap:RAM a disappearing standard too because swap isn't used
much anymore?

I'd be curious to hear from admins that run systems with under 128GB ram
and admins that run really large memory sun boxes too... how do you handle
swap on systems with a bunch of RAM?

I'll summarize what I get back...

Thanks all!
