Is there a performance hit when the "Description Property" is enable with Shared Variables?

[fps]

Hello,

I tried searching for information on the "Description Property" for network shared variables with no luck. Can someone please detail what this property is used for and how it works?

It's a field where you can enter more information about what the particular shared variable is used for.  It would be for good code documentation.  Why do you think there would be a performance hit?

Yes, I gathered that would be its primary use. Is the description transmitted with the data? Why have the "Description Enable" setting if it is used only for code documentation?

What is the purpose of the "Enable Description" check box? Is there a performace hit with it checked?

There is no performance hit from enabling the shared variable description. The description field provides a place to store variable documentation for development purposes. While it is deployed in the local shared variable engine, it is not published with variable updates in any way, and is not remotely accessible.
It can be accessed locally through the variable properties dialogue in your project, or via a "Description" property node on a DSC shared variable refnum (the property will return an error if run on a remote SV client).
