I'm glad Michael Hrivnak mentioned darksky.org. This is a real help to astronomers!
I'll first say, laptops are an exception due to the needs of hibernation. In server environments, I run with none or minimal swap. I started experimenting years ago when I was managing VMWare ESX. Since the ESX host box already had a decent sized swap, I found that I could reduce swap (or page file for Windows) on my guests. My theory here was that only the Host OS knows the real hardware situation. Swap is really a function of hardware - limited RAM to be exact. On systems where I have abundant amounts of RAM, I never see swapping occur. That's my brief explanation.
