[rules-users] column binding vs field binding - any performance implications?

[Edson Tirelli]

  Vlad,

No noticeable difference in binding fields or columns, but there are 
really negative perf impacts in using eval(). I'm writing a blog about 
it. Please try to avoid. I know bellow is just a sample, but it would be 
so much better if written:

Record( field == "xxx" )
