Is it based on memory? It's a common mistake for people to think that swap space should be reserved as a function of the amount of main memory. It's really not related to that except perhaps to suggest a minimum (you should always have at least as much swap as RAM). The basic rule is that you need enough swap space for your applications to run and not run out. These days for desktop systems and many server systems, this figure seems to be around 250-300MB, but could be more or less depending on what you're trying to do. >How has the swap requirement changed from previous versions? It hasn't changed much. There's a natural tendency, however, for applications to get larger over time as new features are added, etc., so you should plan for this. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
