Anything not used by Java and MySQL is available to the OS and it'll use it as a filesystem cache. This is still a big win for Zimbra as so much of its data (everything that doesn't live in MySQL) is file-based. So it can keep all of the most recent messages *and* the big Lucene index files cached up in RAM.

That said, we'll be running with 32gb of ram and I'd sure like to be able to use more than just a few gb of that for Java. We'll have to play around with the garbage collection settings to see if we can come up with anything..
