cram in zimbra (jetty) with tomcat (confluence) on 2GB RAM box? tweak jvm or buy ram?

[gettyless]

I have an old'ish 1U I've been using as a personal server - I have confluence running on it currently, which runs off tomcat. That already eats up enough ram as it is. I'd like to cram Zimbra onto it - and if both run the system starts swapping. I shutdown confluence, and I can get to zimbra.

Should I bother figuring how to tweak the JVM settings on both, or just throw more RAM at it? Max is 12GB, I'm at 2GB -- might as well no? DDR333 and DDR400 are cheap.

Any advice?

There's no real time constraint - so I don't mind figuring out how to tweak Zimbra's memory usage to a minimum, if possible. Is this up to date?

Your best course of action would be to add more RAM, the more you add the better your experience will be.
