Using network rendering speed the render since you have the compute power of other cpu's. I can use 2 computers at home (one can be used has 2, it's a dual processor Pentium), so i have like 3 cpu's with network rendering and it goes fast, depending on the render settings of course. But when i want to see a image on the screen with better result than the preview, i use the network rendering with good quality render and let it go. If you any info, tell us Pleiades
