Jason, Thanks for the vpbmaster tip. I thought it only applied to multiple systems... I guess I need to read things a little better ;) My database creation times went down dramatically now that all 8 cores are being utilized. I went ahead and launched a build with a decent amount of imagery and DTED data before I left work. Hopefully my hard drive doesn't fill up before it gets done. I'm having another hard drive installed tomorrow so that I can run a bigger set of data over the weekend.
I haven't tried creating the overviews yet. How do they help increase speed? If the explanation is more of a class than a simple response then don't worry about responding, I understand ;) Thanks for all your help!
