First core is peaking...other 5 at less than half load

I'm interested in knowing the answer/solution to your question as well, Sharke. I often see this happening to me, and then I wind up having to freeze tracks in order to avoid that first core from peaking out... the others barely break a sweat most of the time. Seems to me a big waste of resources to start clicking and stuttering when we have power to spare in the other cores.

I've got this note copied somewhere in the forum for multi core processor setting :

Thread balancing for multi-core processore
To edit inside Sonar->Preference->Configuration file

To edit ini file direct :
\program files\cakewalk\--sonar--version--\cakewalk user data\--sonar--version\
File : AUD.INI -> ThreadSchedulingModel=<0,1,2>
0 = Same as previous versions of SONAR. 
1 = (default) Better thread balance. Model is more efficient and can provide cycles for other tasks. 
2 = Additional worker thread is created. This may result in improvement with Quad processor systems or higher. Not recommended for Dual processor systems. 

some programs see better results if you open task manager and setting priority to high or realtime.

i remember seeing in another thread i think about aufiosnap and rendering esp bounce to clip that the izotope audio algorithms that cake licenses  only use one core. which is why mixing down some audio takes a while.

I have a problem since changing that thread parameter to 2. Ever since then, whenever I load up the project I was working on when I changed it, Sonar tells me that one of my synths is connected to a silent output and therefore won't be heard. It's not though, it's output to the master bus and sounds as normal. I'm a bit worried (and irritated) by this error message every time I load the project though. 

You live in NYC and you are worried and irritated by a program warning message? Maybe a break from SONAR might be the ticket. If it gets to be too much set the initialization file variable WarnSilentBuses to 0.

I may live in NYC, but I am a gentle baa-lamb imbued with the sweetness of hearts and flowers 

Try increasing the soundcard buffer size? More latency but less load. 
AFAIK the 1st core always loads more, at least it does on my AMD phenom II X6 1055T so if there is a solution then I'd love to hear it. Threadschedulingmodel setting make little to no difference. I am using win 8 fresh install and no change in load from win 7.

I have my setting of this parameter at 2 as well and so far did not encounter this issue. 

Does it occur in other projects ? Could it be due to one of the synth that was removed ?

     Edit - I should have read your reply better before posting. If you are using a lot of 32 bit plugins, I believe you can get Bitbridge to assign specific "servers" to instances of particular plugins which consume more CPU cycles. I don't know what the correlation between Bitbridge servers and CPU core activity is though - but maybe worth looking at.

Sorry for the misread in your reply, Sharke.
