I have some questions about best way to manage CPU usage related with parallel processing. I read time ago, that parallel processing option from Max preferences (Enable Mixer Parallel Processing) only works when you are using different top level patchers and in that case, every top level patcher uses a different audio thread (feel free to correct me if i’m wrong, i am only reproducing what i think is correct).

First at all: What happens in case you are not using different top level patchers? I mean, parallel processing is not allowed but, you are literally using 25% of your CPU power? (in case you have a quad core CPU) or you are using full power but everything processed in one thread, thus, like 4 brains solving the same problem of a task, instead of 4 brains solving different problems to accomplish the same task?

The other question is about poly~ @parallel: I’m managing a pretty heavy patch using different 1 voice poly~ as modules…so they are going in and out dinamically. I’am just wandering how to manage the CPU to get the best performance, so my question is this:

If i have several poly~ objects, 1 voice each and i set them with @parallel 1…will this affect CPU usage? I mean…will my CPU be processing them as 1 poly 1 thread or all the poly~ objects will be processed in the same audio thread?
