i'm using zimbra as a personal deployment for friends/family (less than 10 people).

i'm running it on ubuntu hardy / amd 64 3000 / 1GB ram

i'm quite happy with the install, and i would just like to tweak things a bit to better fit my needs. i've noticed quite a bit of memory, hard drive usage since installing zimbra, and i'm certain i can bring it down.

there appear to be many threads running for getty, amivsd, zmlogger that are probably uncessary for my use case.

my question is, how can i decrease the amount of threads running for these various processes, and what are other ways can i tweak down zimbra to better suit my needs?

and yes, i'll consider throwing in another 1GB of RAM...
