Efficiency and Attribute references

I am always looking for the most efficient way to build an AF Model from the perspective of maintenance and performance. As I look at models developed by other designers, I find a variety of methods for accomplishing similar tasks.

Consider referencing a value from another AF Attribute. At least three methods come to mind for getting this data.

 

1. Formula - A=Path|Attribute;[A]

2. String Builder - ..\|Attribute

3. PI Point - \\Server\Tagname

 

The String Builder DR doesn't allow UOM conversions or being available for use in calculations. These are obvious shortcomings.

From an efficiency perspective, which of these methods provides the best overall performance?

 

I look forward to hearing from you.
