Ok, you got me wondering.Gordon said he put a render node on at install, which you can do tho it says not to. Carrara has hyper threading support as an option. Are you saying to put a node and carrara on a hyperthread pc to improve rendering?(I am assuming this is your only pc w/ this) Generally, they say carrara then nodes on other cpus/pc's.(You get 5 nodes with pro, I thought).

No need to think outside the box....
