no parallel speed up ?

Hi, 

Apologies if this is a rather naive query but I'm extremely new to chromium ...

I'm trying to see if I can use a Linux cluster to parallel rendering. I've
tried the atlantis application with crdemo.conf and crdemo_full.conf but
as far as I can see the full version with two tiles seems to produce the same
frame rate as the single tile version with crdemo.conf. I've got the crserver's
and the crappfaker running on separate nodes but the frame rate stays around
10 fps. I'm I missing something here ? Is there are bottleneck somewhere ?
Are there any other demo's that can demonstrate an parallel speedup ???

thanks in advance,
