Custom PIO - Nested symbol vs. Multiple objects

[Mike C]

I have a couple of custom PIOs that incorporate 2 to 15 hybrid symbols and objects. There can be over a hundred instances of the PIO in the same configuration on a drawing.

Is there a significant benefit from a rendering/processing perspective if the first instance of the PIO creates a nested symbol of the multiple objects, and then subsequent instances of the PIO would merely use the nested symbol. Or does the fact that they're still multiple instances of a PIO negate the benefit?

Thanks.
