You say you are doing "simple 3D text"?
Are you in Classic 3D or Ray-Traced 3D?
RayTrace is going to be slower as it is raytracing all of the text -- you can reduce the rays being used, or you can switch to Classic 3D unless you need extruded text. I usually recommend using Classic 3D unless the effects you want to use require the Ray-Traced mode.
Properly set up and using the same settings I'm finding CS6 faster than CS5.5 or CS5 on all of my Macs'.
Please check your settings sounds like you have ray traced rendering selected.
Many thanks for your help.
Maybe I should share all my settings within the AE panel and, that way it may be easier for people to point things out?,

Ray tracing is CPU

Hope this will help.
I do have one thing to point out - Multiprocessor support should be tweaked so that you have 3 GB per CPU. Best method is to limit the CPUs used by AE.
The 3 GB per CPU makes a substential difference to the rendering time.
I would have thought the more the cpu ther better. well, wrong again.
Thanks for the tip
CPU optimization is hard. You can easily choke the system by allocating too much memory and too many processor cores to the process. Other things always have to run in the background just to keep things like delivering the frames to the hard drive working smoothly.
