Hi All.
I have done a few tests with small render files that took about 60 seconds to render straight out of EI. The scene has a simple sphere with raytraced sub surface scattering, 2 lights, global raytraced reflections and GI, rendered at half Hi def size (960 x 540). The machine configuration is Mac OS 10.4.10, 2 x 3Ghz Dual core Intel, 4GB RAM.
I found that with the local and 3 slaves (2 intances of rama on the main hard disk and 2 instances on an external drive) 4 frames rendered simultaneously in 60 Seconds, effectivly quartering the render times! So it seems that the dual processors and dual cores are all being utilised in this situation.
I have also loaded 4 instances of renderama slave onto an identical mac on the network and found that both machines running 8 frames of the animation completed all in 60 seconds.
This may be trivial to some but it is a great time saver for us, so hopefully it is useful to someone else and hopefully I have put it into terms that others can understand, like me!
