Rotorboy,
I notice you never posted your Zimbra version, just your OS. Adding the version information may help.
However the issue of RAM as you show it does not seem to mirror the usage most folks experience. My own system supports 35 users on an old Pentium-III 1.4GHz with 2GB and I never see the swap get touched. However, even when I was testing with 2 users, the system ground terribly until I upped the RAM to 2 GB; that really seems to be a magic number for even eval usage, and the RAM doesn't seem to get hit that much harder for 20-30 users than it does on idle, in my system at least.
I am wondering if your VM/VPS may be part of the problem. While I know people do run Zimbra in VMWare and probably other virtual systems as well, I also have observed odd problems for some VM users that don't show up in a vanilla OS installed on a hardware machine. Just a guess and maybe wildly off base, but worth thinking about. . .
Cheers,
