[PD] How to reduce CPU use on unused subpatches-abstracts?

[Mario Mey]

Thanks, Roman, but I'm already using [switch~] inside each FX, to stop 
processing the signal. I learned it some time ago, from here:

http://puredata.hurleur.com/viewtopic.php?pid=35939#p35939

But I think that [receive~] and [throw~] are still using CPU.

I didn't try to use inlet~ and outlet~, because I have to make 400 
conections at hand... that's why I asking first. If it will work, I'll 
do it (or find a way to automatically do it)
