This has very much not been the typical deployment for this server.  
That is not to say that it cannot be made to run in a small space - just 
that not much effort has been put into finding out.

In general turn things off that that you don't need /e.g./ disable 
plugins that provide features you do not need.  Reduce the size of or 
turn off the entry cache, in the default case it makes a reasonable 
guess at what useful a cache size would be for good performance.  If you 
are seriously hard up for ram you might consider removing schema files 
you do not need.

Let us know how lean you get it and what you did :)
