Memory requirements of running multiple Grails apps?
I only have real world experience so far of running a single Grails web application per Tomcat server, and I've got a good feel for what the memory requirements are for this. I'm interested in hearing how the memory requirements increase when you start adding further Grails web applications. For example, I don't imagine that if you have two applications, you require twice the memory, because a lot is shared - it's probably not linear. I'm looking into hosting and am just trying to get a feel for these things, so any rough rules-of-thumb would be appreciated.
