Yep, i don't see any swapping happening, I also don't expect a large amount
of users (Maximum 5 at any given time) and we only have 19 entries in the
database so far. The database is on the same host.

We are expecting about 1200 tickets at max per year for the current set up.
I would've thought that RT would be able to manage that much load with 613
MB or RAM.

How much RAM do you think I would need for a setup like this?

I have just switched over Apache from Worker to Prefork to see if that
makes any difference.
