Performance of HDAs vs default nulls and bones.

[Tralen]

Greetings,

I have a conventional null and bone hierarchy, using the default nodes provided by Houdini. I would like to replace them, however, with my own HDAs, that have the same exact internal structure, one for bones, another for nulls.

The reason is that I want to add extra parameters and scripting to the nulls and bones, and it is easier to do it on HDAs. So far, I haven't seen any difference in performance, but I fear that it will drop, once the size of the hierarchy increases.

Is that a valid concern? That a default node will outperform a HDA with identical internal structure, for the sole reason of this being a HDA?

Thanks in advance.
