Downloaded the new update early and loaded up the Abbey Road Drums in Kontakt. They have long bee a source of grief for overworking the first core at low latency. With the new update to SPLAT I'm happy to report things are VERY even across all 8 cores, first time that's ever happened. Thanks bakers....love this update just for this feature!
 

Yeah this feature seems to be working VERY well on my end too!

Hi. It works like a charm here as well. All cores are quite even, and seems more effective.
All the best.

I can only say it has been a long time since I have seen Sonar handle so many VST's so well.  It just seemed to me as we progressed from X1 (producer..., X2 on up, from 32 to 64 bit, sonar was "straining" to run VST's that formerly ran well in the quantities that I want to run.
 
Thanks Cake for tackling load balancing for VST's.  It's working fantastic on my system; it's like an engine super charger.
 
THANKS!

I don't know if this is the right place to ask, but I'll give it a shot. 
 
Does anyone know why load balancing only applies to buffers set at 256 samples or above?  If seems it would be even more powerful at lower settings.

We do this to avoid it being too aggressive on the CPU. If you want to experiment with more aggressive load balancing, you can tweak the MinPluginLoadBalancingBufferSamples setting all the way down to 32 samples. It defaults to 128 samples where it wont load balance unless the audio buffer size is at least 2x that. Its described in the documentation.
 
Keep in mind that load balancing is not a cpu saver. Its actually the opposite, it attempts to use as much available CPU power to get the job done faster. For audio processing, finishing the job faster means fewer dropouts even with high loads. With more aggressive load balancing you can get diminishing returns esp with projects that are already very high load. Hence we chose to keep the default settings moderate. 

Fantastic results!

Before...

After...

Have to post again, this new feature is absolutely astounding!

I notice now that core 1 often has nothing to do, will adjusting minpluginloadbalancingbuffersamples make it kick in earlier/later?

Excellent update Bakers!! Thanks.

After seeing these posts I'm looking forward to setting some time aside to understand this feature, so thanks for the comments. I've been having some trouble with some new Waves plugs that have been bringing things to a grinding halt and this sounds like a possible way of dealing with it. Thanks again.
