Just had to celebrate something. My render time for a feature-length DV project on my old Dell 8200 was 27 hours. It was a hot rod when first purchased, just before that newfangled HT enhancement came out.
Now, I have invested a rare company bonus into a Mac Pro, a quad Xeon 2.66, 2GB RAM, running XP Pro on Boot Camp. Vegas automatically defaulted to use all four threads to render, and rendering the film from a firewire source drive onto the same hard drive that the OS's are installed on, reduced the render time to 6 hours.
That's not the punch line. I just plugged in a newly arrived SATA 3GB internal drive into one of the Mac's bays, formattted it and rendered to it.
Render time is 3 hours. Unbelievable.
