[PD] benefits of planet ccrma kernel, and realtime priority pd?

[Mike Wozniewski]

Thanks for the responses.

I really wanted to see if it was worth it to go through with the CCRMA 
kernel install.

By just the kernel, I meant I didn't want to install any of the 
packages. We are building a pretty heavy application with Pd+Gem. We 
already have a decently working system. But any extra performance we can 
get out of our current machines is beneficial. The graphics end is quite 
optimized - so now I'm focusing on audio. I was wondering what kind of 
benefit CCRMA could give. It seems from the emails that it's more of a 
convenience benefit than performance (ie, it's easier to download 
packages, run -rt without being root, etc.)... If I can run pd as root 
anyway, it's not going to benefit me that much right?

I guess though, that latency is a bit different from performance. It 
sounds like the latency can be cut down a bit by CCRMA. Performance 
however - ie, CPU load - is unaffected right? Julien, you said that 
operating at lower latencies you get clicks when CPU load >80% ...does 
this mean that in fact low latency might hinder a heavily loaded 
application?

Thanks again for your responses,
