[PD] graph on parent problem?

If I understood your problem correctly, this might be because pd redraws
array contents very inefficiently, so if you are constantly changing array
contents that can prove quite cpu intensive. Similarly, moving such gop
patch requires complete redraw of all its contents. Pd-l2ork fixes latter
problem by moving such structures via tag, rather than redrawing everything
(so in pd-l2ork moving such gop structure would be one instead of
potentially thousands of commands), but the former problem is something
that can be only solved by rewriting or getting rid of the networked
gui-dsp communication protocol.
