One more performance tip:

Defragment your hard drives. When hard drive is mostly full it gets fragmented and any large file spans multiple fragments scattered on entire hard drive. This causes excessive HDD head seeks and it can be heard as "churning".

If you hear hard drive churning for few seconds when you do something with your database, it's a sign that your hard drive may need degragmenting. It will help performance in any application, not just OrangeCD.
