Okay, I restarted my computer and left the normal stuff running in the back ground. This computer is about 2 years old.
CPU = Intel C2D 2.53 GHz
RAM 3GB (actually 4gb, but running Vista Ultimate 32-bit)

I did two things, created a quick project in Prodigy Composer. I then took and didn't change anything just resaved and built the project in SB. The speeds were much quicker on this desktop than on the Crestron Dell Laptop

Composer to SB = right at 10 minutes
Build in SB = 6 min 17 seconds

Here's a link to the Composer folder (zipped):

And here's link the the SB archive:

Hopefully this works and we can get some comparisons.
