I am not really a power user, but I haven' t had latency problems 
before, so maybe this is not the central problem (but I understand that 
you may be right and I could improve performance with a kernel change, 
only that, if I can solve this latency problem in an easyer 
inside-puredata way, I will leave it for a later macro-system optimizing

As Iohannes lets think, I use xfce for its lightness and minimalistic 
user interface. I hope there is not a problem in the interaction between 
puredata and xubuntu's xfce environment.

Thank you, I will substitute the before-master audio mixing with this 
object and see if the problem solves, at least as an alternative try.
Gracias, y mejores deseos
