"Many readers already are thinking they know what to do: throw in as much RAM as you can afford and configure little or no swap space. For many systems with a lot of RAM, this works great; however, very few people realize that Linux makes this possible by using a form of memory accounting that can lead to system instabilities that are unacceptable for production environments."
Idezet2:
"Swap space does not inherently slow down your system. In fact, not having swap space doesn't mean you won't swap pages. It merely means that Linux has fewer choices about what RAM can be reused when a demand hits. Thus, it is possible for the throughput of a system that has no swap space to be lower than that of a system that has some."
