circuit performance

[stuff3d]

Mine first plug in is almost ready, does have,
however, still performance problem with Circuit.
what can I still save in this Circuit, or do better?
graphical surface I had to remove to upload,
because this is too big, nevertheless,
she is not for high dsp use responsibly.
If I mixer stm 4896 use , spent this 4x less dsp.

For help I would be grateful.
