Hi Betina,
Another simple thing that comes to mind is to "vacuum full analyze"
(assuming you are using postgres). This seems to greatly improve
Apollo load times for me.

You could also try performance tuning your db server:

http://www.revsys.com/writings/postgresql-performance.html

assuming you have more resources, memory to give. I've managed to get
my load times down slightly this way.

HTH,
