NameValueSet and Identifiers

More like a basic C++ question than anything, but in my code I do this a lot:

myNamedValueSet.getWithDefault("MyValue", 999);

I have about 100 named values I use. Is it better to create static identifier objects for my values and pass them to the getWithDefault() method, or does it matter? Is passing strings directly to the NameValueSet method less efficient?

Yes, using static identifiers will be much faster. Whether that matters or not depends on what you're doing.

Thanks.
