With RAM, the more the merrier.  I guess the question is, what does this
app do?  What worries me with that is no swap space.  With an app that
takes up that much RAM, I'd be wanting some swap space. But, as I said a
lot depends on what the application does.  If the app doesn't do any
reads/writes from disk, or if there is no possible growth of the app
beyond 8GB, then having no swap would probably be okay. But you have to
keep in mind that the app isn't the only thing running, you have other
kernel services and system services which also take up RAM.  If I were
you, I'd go with more than 10GB and add a couple GB swap space, just to
be safe.
