RT cpu DR only using 50% cpu on slave

[super gnu]

just testing out my new workstation/dr node, both 6 core SB-e i7's

main cpu is pegged at 100%, but the slave ( exact same spec) is only sitting at around 46% cpu usage. its a very simple scene, some balls on a plane with a domelight.

its a very simple scene, some balls on a plane with a domelight.

Yep, that's why. For a simple scene, the network overhead might be larger than the actual time to do calculations.

To improve this, you can try increasing the number of samples per pixel; the default is 4, try 8 or 16 - this will give the cpus more work to do before they pass the results back across the network.
